Tabata squats will focus on muscular endurance- not so much Strength.. Strength is the main goal of lifting weights... The type of muscular endurance developed by lifting weights is generally thought to just benefit your ability to do more reps of weights.

Jump squats are good at converting strength to power- but put you in a fairly dangerous position- especially as weights advance.. It's hard to maintain proper bar position after the catch.

Box Jumps are not bad at developing Power- but as you get better at doing them and begin adding height to them you also get better at pulling your feet up faster and higher to get on the higher box. If you were to watch the progression of an athlete as he reached higher and higher boxes- you could see that his head does not get proportionally higher with each box height increase.. So it does not provide scalable progress..

I'd Chose the Powerclean for Power development... But you will need some instruction
