I have been using Supermemo daily (except for when I miss a day or two, vacations with no desktop, etc) since about 2010. I have found the newer algos to be pretty good. I have not had any bugs or a messed up collection. Its one of the pieces of software that is keeping me on Windows. There is still no foss replacement for incremental reading/writing [1]. Also, Supermemo has two modes that lets you skip a few days without being overloaded [2][3]. So you don't go from 20-30 cards to 200 if you skip a day.
That being said, its just another tool in the toolkit for learning stuff. I don't think I'm that much smarter or better at anything just because I have used Supermemo often for awhile. Honestly, I just like making cards and throwing articles I want to read later into Supermemo for processing. Most of what I use Supermemo for is incremental reading, which I have never been able to find a good replacement for. I like being reminded of cool stuff I have read and ideas that I have had. I would recommend also learning and practicing various mnemonic techniques alongside spaced repetition.
Most of the other algos/apps I have tried have been okay, I have not tried FSRS because I don't really use Anki anymore. I used Anki when I was in college for about 2-3 years because I would do flashcards using the mobile app. I was still using Supermemo daily during the same time period though.
I also use Clozemaster for language vocab with Supermemo. I put the sentences and some explanations into Supermemo after I do them in Clozemaster. I do not really consider myself to be a language learner or learning a language. I pick up new vocab very slowly and do not do anything else to practice the languages I am learning vocab from. I have also been using Math Academy almost daily for about seven months which is nice, but definitely not a full replacement for learning math. Using Math Academy actually made me start working with math textbooks and online resources again.
