Both suck! SuperPump250 did nothing for me and I ended up crashing hard. NO-Xplode is over rated and is nothing but a bunch of fillers in my opinion. I agree with 'White Flood', also E-911 from LG. Jack3d is supposed to be the **** and is cheap right now! I just purchased some and can't wait to try it out. Your question is pretty lame as all of them have their differences and will be dependent on what you are looking to get out of it!
