after exploring neovim for a couple days, here are the things on windows 7, 2018-04-20:
terminal inside it seems awesome
config is all bespoke, afaict. running it in terminal (conemu) mode is hard to configure large file search takes forever
pretty decent for dipping the toe in the water of vim on windows. Get's decent windows-y UI.
basic vim support windows native is nice - config is not a total bear
large file support is terrible. There's lots of latency in both opening and then moving around commands are not global for the vim plugin - you have to be in the context of a text editor to use them
