I do, personally, but that might just be because I'm used to xedit, and have a monitor with a reasonably high refresh rate, a keyboard I purchased largely to lower input latency (which I find annoying), and a typing speed that's decent (120wpm).
You can measure input latency relatively easily, but it's not as useful without a frame of reference. Here are a couple internet posts on doing exactly that:
If you're not wanting to go out of your way to measure it, though, there's a pretty straightforward way you can get a feel for it: Pay attention to when the glyph appears on the screen, versus when the click of the keypress happens. For example, in xedit, I press 't', and the appearance of the glyph occurs almost simultaneously with the click. The click and the appearance happen much more noticeably asynchronously with Electron applications, including this one.
