I'm using Pyramid on a daily basis. I'm very happy with how everything performs. Things never get in my way and SQLAlchemy is awesome ORM solution. For me pyramid is the sweet spot between microframeworks and django. The team that manages Pyramid is extremely competant, I've updated my applications over multiple releases without issues over the years. I think what people use often depends on weather you prefer to have choices being made for you with tightly coupled systems vs sane defaults that you can customize to your liking.
