Pretty favorably. He liked the length, flexibility, and heat resistance.
I've compared Steven's gloves to the welding gloves I use (and I only buy 'em when they are on sale at $5 a pair). Steven's gloves have much longer gauntlets so that in itself is enough reason to get a pair. The basic welding gloves only reach 1/3 of the way up my wrists.
They're also just as flexible and heat-resistant as the welding gloves I use and that's really saying something. As an example of how heat-resistant they are here's an example: I use my gloves to pick up burning lump charcoal and briquettes and to grab hot grates right off the grill, and Steven's gloves will work just as well. Try that with a silicone glove and you may just burn it.
Keep in mind, though, that the times I picked up hot coals were emergencies. (Some guest's kid ran off with my dedicated fire tongs). Don't try this at home.
