I've worked with many productive people and the speed they write code at never was a big factor. The first thing you should optimize for is the speed you read code at, that makes a big difference, so look for tools or IDE's that helps you explore and read code faster. Debuggers, jump to reference, lookup usages of symbols and so on are all very important things to have.

The time spent doing input is a tiny fraction of time spent coding, yes. However, it is all wasted time, and reducing it leaves more time free for thinking.

There are many syntax-aware vim verbs (ci[ or ci” for example) that save a lot of time and let me get back faster to thinking about the what and not the how. Too much time on the how and my ADD kicks in, sure as someone walking into my office and trying to talk to me.

Can confirm. I prefer using Vim because it makes writing stuff fun. Never thought I could ever write for fun.
