Thanks for the flame pm thread... I didn't actually read your post cuz I thought you were a troll.
To answer your question;
You need to do both if you want to get strong. Period. They will compliment each other in too many ways to ignore one over the other.
Strength takes time, you can't fast forward progress, unless you're using some kind of PEDs. If you want true strength, balance your training week, lift consistently for a LONG time (10+ years), and eat enough to support energy levels and accumulate adequate protein for muscular repair.
lmk if you want a proven percentage program (11-12 week linear periodization, undulated twice) for all the slow lifts.
