Same here, since Firefox v0.8. Hated IE. Never took a liking to Chrome and now Edge. Had issues with Brave and Vivaldi when I tried them a couple of years ago. Like Opera, but as mentioned elsewhere in this thread, sold in 2016 to a Chinese company.
Brave is very good. Very light on resources. Has a Tor browser, which will become important very soon.
Has Brave improved much in the past couple of years? There were some issues back then that bothered me. I also didn't like I couldn't tailor the browser much to my preferences. I guess I've been a fan of the addons for Firefox, although they crippled several good ones when they changed their browser around v54.
MS Edge is pretty decent. Chrome internals and can use Chrome addins.
