Well, I cannot vouch for the longevity of either, but when the higher model Boss amps are functional they are adequate - I'm specifically refering to the Overdrive series. The difference between my JBL 1200.1 powering two perfects, and that sub power the same two subs is not huge. The Boss was a little more hairy, but other than that, they sounded similar. Now, for the price of the Overdrive amps, you could get some very nice, respectable brand name amps out there.
