The question should not be which one is a good price which one fits the best. So far the only aftermarket weatherstripping I like is Metro. The GM T-top weatherstripping is discontinued but runs about $400 if you can find someone selling it. I have a friend who redid the weatherstipping on his car and the GM NOS cracked after about a year It was not garage kept. So I would just live with whatever you have until someone makes a good set. Unless you have bad rust issues.
Goodluck!!
