ampeg if you want a warmer tone, hartke if you want a sharp attack. Both are nice. The ampeg kickback is a bit of a hassle because it is a little short for that style of casters. The ampeg being 4 ohm is also going to limit stacking two later if you get a bigger head unit. I still recently traded a hartke 410xl for a svt410hlf despite these things, because I really like the ampeg sound. My money is on the ampeg. You can find them used for under 500$ easily.
boo...
