Jack3d honestly gives me better energy then both but i crash on jack3d pretty hard some people like noxplode but there are better options, as far as PWO sups go ive ventured off most of it is hit or miss and im not up for spending money to find the right one going from what ive experienced Just bulk Beta Alaline PWO for strength and endurance is all i use atm with BCAA's during.
As far as your question goes Ive never tried superpump 250 i have tried noxplode its not bad i think jack3d is better but i honestly can't stand the flavor of jack3d im not sure if im only one some people like it but its like some sort of household cleaner even 4 oz is really hard to down. Like i said earlier check some bulk products and maybe make your own PWO of what works for you, as far as other options go some people really love jack3d the energy is great, maniac seems solid.
As far as PWO supps go it really is hit or miss with them your gonna have to find the one that works for you i just ordered some Incarnate which is dosed pre and post workout its beta a and joint support expecting good from it.
