i'm not a fan of synthetic leather, ok you got the mma style bag gloves (fingers a free), the bag mitt(just like a mitt like the link you posted), and the bag gloves. i think protection wise the bag gloves would be the best as they are pretty much a pair of full out boxing gloves just a bit more durable, but if you need to grapple and get a grip on your opponent mma style gloves are perfect, the bag mitts are kinda in between the 2 doesn't have the protection of a bag gloves and you don't have the dexterity of an mma glove. but then again i was was able to do some bjj in full out boxing gloves to protect my broken finger 2years back, and i really got good at not relying on my grip to trap limbs and stuff.
here's a quick link of our bag gloves we don't have the bag gloves just the mitts and mma style gloves, just giving you an idea of what i'm talking about
