I honestly dont think it matters what u do in the gym. As long as over time you PROGRESS!
Progression is the key, if your lifts are constantly improving, it really doesnt matter what you do, HIT, OVT, Max OT whatever, it doesnt matter.
If someone is squating 225 for 10 reps right now and in six months is squatting 315 for 10 reps, i guarantee his legs will be bigger!
I think people make this shit too complicated, when its really not. Train hard, improving every training session ( when possible ), eat good clean foods 90% of the time,and dont become obsessive with it ( bodybuilding ) because it will ruin you and your social life.
