I focused more on the finishes matching. I was lucky enough to find a potfiller that was from the same group as my sink faucet.

My finishes are the same but the products are very different. I have franke for mynpot filler and love love love it but my faucet on the main sink is kwc systema and I think the prep sink is danze...I forget but each was chosen for function over form.

I have a Grohe Bridgeford pull-down at the sink and a Blanco Terra potfiller. The finishes are similar (both nickel) and there's a vague similarity in the roundness of the handles. That makes them work together fine in my opinion. I just wouldn't put two wildly different styles together...a Kohler Karbon and a Victorian looking Rohl cross handled potfiller, for example.

The apron sink is copper, and made by Rachiele. The faucet is Delta Victorian in Venetian Bronze, but the pot filler that I've found is made by Belle Foret, and is tumbled bronze (it looks like copper). I don't know if Belle Foret is a good quality brand, though. So the finishes are not very similar. Delta is almost ORB, and the other one looks like dark copper. The style of both are the same, though. Whaddaya think? Close enough, or should I keep looking?

My main faucet and potfiller are both chrome, but different brands. The have some similar design detai;s, but they don't match. The prep sink is a brushed nickel. I wanted a shining sparkle in front of my window and against the tile and marble, but I wanted a softer contrast against the black on my island.

I'd look at what else you will be seeing when you look at the faucets, where they are located in relation to each other and other elements in the kitchen and consider that you might want to go intentionally different if they are going to be noticeably different. . On the other hand, if they are not next to each other, they may be similar enough that your eye will fill in the difference.

I have three faucets, all different in style but coincidentally all Kohler. The finishes are the same and that's the key thing IMO.

Ours will be totally different. They are across the room from each other. My range is against a stone wall (the back of our fpl). I wanted the potfiller to look like an outside spigot. I chose the item below. It will also have exposed plumbing braced against the stone.

My kitchen is all neutral - no color no pattern. I am using antique brass hardware on a built in hutch, and polished nickel on some cabs, and orb on my "general store counter". My range is matte black with nickel and brass trim. My faucets are nickel and wood.

Not too much matches in our house! Of course we are an extreme situation. I would say if your filler is on the same wall as your faucet, they should be in the same finish and style.

PS I know my filler is not a filler and some will say it wont work because it does not extend. However in my old kitchen I had a filler for 8 years and my experience was that I just used the nearest burner when I wanted to use the potfiller. ALmost never had a case where I needed to extend it. Also, my new range is open on all sides so its not hard to reach the pf in a rare circumstance where I want to do something different...

Finishes should match, as should the spirit of the designs. However, you've got a bigger issue. You're using an OTR if I recall, and OTRs come down much further into the backsplash space, and this really doesn't leave enough room for a pot filler. And, stylistically, it doesn't work. Potfillers are a "pro" kitchen look, while OTRs are definately not. They're for smaller space challenged kitchens that have no other option for ventilation. You need to reconsider your ventilation issues before deciding on a pot filler.

Since my PF emerges from a stainless backsplash, I ordered it in stainless, not polished nickel like the rest of the fittings.

This is interesting, especially what Live Wire Oak said. I do need a pot filler, though, since my cooktop will be across the kitchen from my faucet. However, I see nothing wrong with an OTR microwave, and just because I have one does not mean I should not get a pot filler, unless it truly would not fit. Live Wire, you seem like a very intelligent person, but relax about my microwave. :o)

Like most my finishes are the same but different brands (chrome). I have a 48" range and the farthest 2 burners from the potfiller are 22K BTUs so I wanted a pot filler to reach both burners. Not many out there so make sure you measure. Also, it doesn't necessarily have to make it to the middle of the burner but enough to fill a pot.

LiveWireOak makes a valid point. If I had an OTR microwave my potfiller would not fit if I wanted to be able to fill all my pots. The extremely tall ones for lobsters and corn (that's where the potfiller really comes in handy) would not have enough clearance between the potfiller and OTR microwave. You should measure your biggest pot and add a few inches above it for clearance. The nozzle end may be lower than the rest of the fixture so that pushes the OTR microwave even higher.

Typical pot filler height is 16"-18" from the counter height in order to be able to fill taller stock pots as in this image below.

You can have an OTR or a pot filler, but there really isn't space for both.

Yeah... I took Live Wire's advice and am forgoing a pot filler, but to do that I made a huge change to my kitchen layout. I read elsewhere on GW that it doesn't make sense to have a cooktop far from the sink, because then I'd have to lug heavy, boiling pots of pasta back to drain in a colander. Plus, someone mentioned the risk of turning the pot filler on, getting distracted, and forgetting that he water was on.
No pot filler for me, after all.
