I'm glad it's working for you. I use v8 every day on my work machine. My complaints aren't about the speed of the application, but rather the reduced features and removal of any menubar app functionality that was present in v7. I'm not a fan of the UI changes, personally; I don't know why everything needs to have _so much_ space, but I could ignore that.

Don't get me wrong, I'm not a fan of Electron, and I'd prefer it have remained a native app, but that alone wouldn't be enough for me to jump ship. And I'm not even claiming alternatives are better than v8; it's simply that v7 was much better, and I'm actively looking for alternatives.
