For me it would be snap on. I can get them every Friday from the truck, and can get warranty every Friday if I ever need to.
Don't have a clue where I would get hazet.
Even better, I can just go out to my road box, already have the snap on 3/8 deep well in there! They've served me well for 10 to 15 years. They were my first snap on set, convinced me that it would be worthwhile to look for more, so eventually I got a full set of 1/4". I still prefer my proto in 1/2" drive. I think I've broken only one of the 3/8" set in the time I've had them, it was a 1/2". I've also broken one or two of the Proto 1/2" deep in that time, so it might be a size vs strength thing for that particular socket.
The hazet might be better for you if they're available. I can't even see them to compare, so not going to work for me.
