Comfort: I'm only going off of what i've used here so i can't say how they compare to other gloves. These gloves are very comfortable. They are pretty much as comfortable as the Empire Grinds but without sacrificing any protection.
Protection: Of all the gloves that i've used these have the most protection. I have taken shots to the hands with these on and felt no pain whatsoever. Unlike the Grinds that don't have much protection. But the padding, etc., do not inhibite movement at all.
Quality: The quality of these gloves is amazing. Unlike my JT's they aren't falling apart after a few months of use. I've clipped off the first half of the fingers and they aren't unraveling or falling apart at all.
These are by far the best gloves i've used. well worth the price. Proto makes great gear/apparel. i definitly recommend them.
