5/3/1 works. Did 3 months straight not very long ago and the strength is virtually assured if you put into it what any good routine takes to succeed. But it can be extremely boring, and the progression is tediously slow.
5/3/1 was really user-friendly, and guaranteed progress is better than none if you aren't making any. But if you're still getting stronger without it I might hold off. But do try it at some point!
