I used to use 3ds Max and I find the Blender's UI really terrible after years of occasional use. It's very unintuitive and you'll have to learn everything from tutorials / reading Blender forums. It seems to have many annoying quirks, which make me angry every time I use it.
how did you learn 3ds Max?
I read tutorials, but the UI was also more intuitive / discoverable than Blender. It's been over 20 years since I last used it though, but I remember it being much easier to use than Blender today. I could model, texture and animate a full game character from scratch by just learning the basic UI.
