Same here. Even if I'm forced to work with non-Vim tools (Visual Studio for example) using their often incomplete Vim-emulations makes lightyears of a difference.
If I had to "criticize" one of Vim's concepts, it would be its way of overriding registers in very unintuitive situations, but I'm certain I'll get used to that, too. When you're aware of it, it's simple to avoid using "_ first.
Edit: OTOH, selecting a piece of text and replacing it with p is quite irritating: The 0 register will still contain its original data, but " will contain the replaced text. I am not aware of how to disable this effect ("_p will paste from the black hole register, which doesn't help in this case).
