I generally start vim in my src folder on Monday and exit it on Friday. Occasionally, just on a whim, I run nvim instead. Mostly its fine. But the times I've experienced crashes or other hickups like rendering bugs forcing me to :qa!, it's been on nvim.
Edit: Oh and I run it in the terminal, iTerm2 to be precise.
