If you're sad RARBG closed, give the qbitorrent search a try.
I searched for ages for a replacement of something like torrentz, and the rarbg drop made me start the search again. I ended up trying the included search in qbittorrent, and I'm very happy with the results, it scans many public trackers, and I have always found what I wanted.
To be clear, qbittorrent is a desktop app for linux/windows/mac, that has a panel where you can search for torrents:
I agree that the search function in Qbittorrent is actually pretty good.
This coming from someone who used to use Waffles and Demonoid all the time. I still use rutracker some, but they don't have nearly as much as the Qbittorrent search.
I also recently got into Soulseek and it's pretty good as well.
Soulseek is one of my favorite applications. The old GUI makes me feel like I'm sailing the high seas of my youth.
I was unaware if it offered anything other than music.
