KDE is a wonderful desktop environment. It's been a while since I've used it but from what I've seen it grows and improves every year.

Gnome is more opinionated. There are fewer options overall, the core apps are generally much simpler, and it assumes a specific way of interacting with your computer. You can change this with extensions, but if you are dead set on a specific workflow and need to venture beyond a small set of widely-used and well-supported extensions then it may feel like you're swimming upstream.

I personally prefer Gnome because I don't mind trying out new workflows and it ended up being a good fit. But I understand why many "hacker types" would prefer KDE, and (assuming they've ironed out stability and release scheduling issues) I agree with other comments that KDE would make for a better default experience, especially for people coming from Windows.

Thankfully, both exist and you can try them and see what works for you!
