I'm not sure Gimp was ever especially good. At one point I suppose they matched up alright with Photoshop and was pretty much the only alternative that didn't outright suck.
These days though there's a lot more options to choose from that are generally pretty good.
I wouldn't be able to offer detailed suggestions since I use them a little infrequently, but a few of what I've used have already been suggested here. Namely, Paint.net and Krita.
There's also some Wikipedia articles and guides out there with some decent info too. Here's an example you can look at, and then you can take a closer look at any programs that seem like a good fit.
And if you're looking for vector-based programs, I'm sure there's another article that should cover that.
