Heritage is more fragrant and has a cabbage flower like a Hybrid Perpetual not like either of the two other roses. However, Austins are tougher for me to grow here. It's one of the hardier Austins. Mme Antoine Mari is a slow repeater, but a lovely Tea rose. Mme Caroline Testout is a great bloomer with classic HT flowers. Not real fragrant. I like all three. You can't really compare them as they are three distinctly different classes of roses.
The only one of the three I have grown is Mme Caroline Testout. I have the climbing form. The thing I like best about it is that it has the most amazing blooms. It is an EARLY hybrid tea (before they wrecked them). The buds are huge and fat, and the flowers are huge round, decadent & blowsy - just amazing. I checked mine yesterday (it is climbing up our chimney). It has made it up to about 20 feet high on the chimney. However, it is not a rampant grower at all, and you could easily keep it much shorter.
It was grown in the thousands in Portland, OR in the early 20th century, so I assume it is somewhat hardy. I got mine as a cutting from one that survived in a nearby yard of a house that was vacant for 7 years, so it received no care whatsoever. It was buried inside of blackberry thicket. Nonetheless, it climbed over a fence and into a tree and bloomed its heart out every Spring - we could see it from our second story windows. Now that the current owner is taking care of it (without any spraying) and feeding it, it re-blooms all Summer. I would highly recommend it.
Of the one's you listed, I only grow Heritage. I've grown it most of the last 15yrs and can only remember 1 year that it wasn't a consistently good performer. Good number of blooms, good repeat, winter hardy with no protection, is thorn-less, and sets hips. I don't have a good sniffer so I can't vouch for fragrance. It's hard for me to be sure, because I spray, but, since I've never seen BS on it, I think it's at least BS resistant. Out of about 20 established roses it's in my top 5.
Mme. Antoine Mari" is one of my 12 favorite Tea roses, for beauty of blossom, leaf, and bush, and Tea is my favorite rose class. The new foliage is purplish and very attractive, and as with nearly all roses of this class re-bloom is quite fast, over an extended bloom season, until the first frost. There are c. 6 or so Tea roses that are slightly more tolerant to cold and M.A.M. is said to be one of them, from Bourbon influence, but I don't know if it can be grown in 6b. Mme. Caroline Testout' is a fine rose, one of the early H.T.s with broad blooms that resemble a Hybrid Perpetual more than most H.T.s. "Heritage" did not perform well in our organic method garden, it was covered with powdery mildew, and was slow to re-bloom, and the petals were damaged by rain.
Of all the pink Austin roses, my favorite is "Mary Rose" for its fragrant pink roses, pretty foliage and more graceful cane growth habit. It was the only Austin rose among 14 different Austin roses that bloomed as early as our Tea roses in spring. "Mary Rose" also produced good re-bloom. - In our garden, near San Francisco, California "Mary Rose" bloomed as often as a Florabunda, producing between 3 and 4 bloom cycles each year.
I grow Climbing Mme Caroline Testout and Mme Antoine Mari - at least I hope MAM is still growing. I moved her recently, and she's looking less than good. The flowers of MCT are amazing, not only large but they stand up and look at you. I tolerate a lot of blackspot from her for those flowers. Fragrance to me is a light cinnamon. {{gwi:242467}}
So far MAM nods too much for my liking so I can't readily see her gorgeous porcelain blooms. And in my garden she doesn't have a lot of foliage. Maybe this year will be different. If not, I have other choices.
I have experience with all three. Two (Heritage and MAM) are still in my garden. These three roses are very different, but all three are beautiful. All three will require spraying in NVA, based on my experience. I am in MD close to VA border. If I had to choose one, I would choose Heritage. You will have a beautiful big bush in 2-3 years. Repeat bloom is very good and fragrance is great. If left unsprayed, it will loose most of its leaves, but Not all and will continue to grow and bloom. MCT gets too much BS, basically 100% leaf loss without regular spraying here. MAM resistance is better, but it will take you 4-5 years to build any decent size bush. Every winter it will have a lot of dieback, the younger the bush the more dieback. So first two years you will start in spring almost form ground zero. And if left w/o spraying, BS will weaken it to the point of questionable hardiness. I love Teas and have more then 10 different ones in my garden, but this is how you start them here. A lot of time and patience is required. My Lady Hillingdon and Safrano and Mrs B R Cant all struggled at first. My MAM (2years in my garden) is still struggling.
