As much as I liked Modo, I was paying a monthly subscription, and now with Blender I don't and it's got this enormous open-source community that provides a lot of long-term confidence, which I wasn't quite getting with Modo. The UI changes going from 2.x to 3.x was pretty important in my decision to switch.
One thing I found helpful when moving 3d modelling softwares was to setup all the keyboard shortcuts to your previous software's bindings, and then you can tackle figuring out the UI, the different object modes and the Blender Way To Do Things™. There's plenty of preference files around on the web that you can plug them in and get going quite quickly
