I'm not a real expert because the Jet is the only band saw I've ever used. I wish it had the mechanism for relieving the tension on the blade with a lever rather than the tension setting knob, but this feature (it can be added on--$150 at Woodcraft) is expensive. Look at the ease of adjusting the upper and lower guides first. I spend most of my time fiddling with those adjustments. Also look at the method for tensioning the blade. On the Jet, probably the Delta too, the knob is at the top of the saw and not terribly handy but I can live with it. The size of the table is important, the bigger the better. The fence is also important. I bought the Fasttrack and love it.
BTW, trash the guide blocks that come with the saw and get Cool Blocks or something similar. They're cheap and much better for the blades and operation of the saw. Good luck.
