I think you'll probably be OK with either one. I like edgecomb gray a bit better. Another very, very similar color to edgecomb gray is SW accessible beige. When getting our main floor painted recently, I nearly chose edgecomb gray, but read it can read ever so slightly pink from time to time, so I went with accessible beige. It might be worth grabbing an accessible beige color strip and comparing it to edgecomb gray. They are quite close, but subtle differences.
Here's accessible beige in a Houzz pic. We've been very pleased with it.
