Difference between 15X and 62X first stages?

[sunny_diver]

Can anyone tell me the difference between the 15X and 62X first stages? The 62X appears to support the Auto Sealing Technology, and is a little larger, but besides that seems to be very similar to the 15X.

Both support TBPs as far as I can tell.
