Roller Pilot Bearing - anyone used one of these?

I bought both from Mancini's to debate which one I wanted to use.

I think I'm going to try the roller one out, but mancini's said there were problems with them wearing out, then other people told me they are the cats meow, so I'm gonna try the roller.

I hear that by putting them in the freezer over night or in dry ice for a while they will pop right into place without needing an install tool.
