Ultra success 5g for sure... I know with 4g you can combine it with luck magnifier.. But then you should listen to each at least 8 hours daily.. For people like me who can't do that and only listen to a sub for 8 hrs daily.. 5g subs work better.. So I'd but the ultra success 5G, the day it is released :-)
