It's one of those things, they'll all be good, but you just have to make the best guess, if you can't try them. Everyone is just going to say what they use is best for X reason.
FWIW, I had a VK 212MNT. Don't be put off by it being rated at only 600w... It's a hugely loud cab and took all a 900w amp had to offer. With very strong lows and clear highs. I went back to Markbass however, and for what I want it does the job far better. Its obviously not a better cab, just better suited to what I need.
