I personally did 5/3/1, but it absolutely is slow and you have to hold back all the time. Not for everyone. I switched to west-side conjugate style after 5 months of 5/3/1 and went from a 205x1 to a 260x1 bench in less than 4 months, added more than 100 pounds to deadlift and squat during that time as well.
It may have been premature for me to start conjugate though.
If I had it all to do over again though, I feel like I would have done starting strength. It is progressive overload though, which only takes you so far, or...your CNS simply won't deal with it.
Skip stronglifts, waste of time in my opinion. There's no magic number reps sets like that program claims.
I have had great results focusing on max efforts followed by technique volume work followed by appropriate assistance work each lift day...and eating well over 3000 calories a day.
