they are all pretty good..
I use Ultra Copper or the red Hi-Temp RTV ,or Ultra Black RTV--but I have used Ultra Blue,and other no name brands that worked well too--I havent done to much motor work lately,so I'm not aware of the newer sealants like this "right stuff" you guys use...
I'd say they are all pretty good,some are better for sealing against oil more than others,some have higher temp resistance,but I cant say I've had any bad luck with any of the RTV sealants I've used,even the "old" original blue goo that came out 20 years ago...
