The SSS wrench is better, hands down. Supposed to be a much harder metal than the Wheelers. Northlander also sells a McCree wrench that is supposed to be pretty good, but i've never used one.
The boltheads from SSS are Savage factory boltheads, just like you would buy from Midway.
FYI, If your target action has a left ejection port, remember you will need a LH bolthead. Fred or Lisa will know what you need though if you call them.
