Never had any issues with Avid tbh. On top of that, if you work in post then you have to have PT Ultimate in order to be able to work seamlessly with the others. Send your sessions over, open anywhere etc. etc.
Of course they could and should do better, no doubt about that. More frequent bug fixes and updates/new features. Havings said that, a lot of features that people area asking, I don't really need because they are for music. And vice versa, features I would love to see, music people don't need. So I suppose Avid can't please everyone.
