Opinions on Hartke amps/cabs?

Just want to start a discussion. Asking because I used an Ampeg (PF500 500 watt head, PF cab) at a small gig recently as the backline which was absolute trash; kept farting and couldn't get loud at all. My Hartke HA3500 350 watt head and 2x10 cabinet can fill a high school gym at 8 ohms, which sounds a little ironic when compared to the higher wattage Ampeg.

Anyway, opinions on Hartke?
