Thanks. The one I linked, according to the link in the OP and BulbFacts, is the GEN2.
The one
@Late Call linked is, according to BulbFacts, a GEN1.
The first post seems to recommend the GEN2, but the last few posts suggest the GEN1 to be a better fit. There's some mention of a bigger boot like this maybe fitting bigger ones:

The general consensus I see here is that GEN1 fits best...correct? Based on that, it's cheaper price, and BulbFacts rating it better is there any reason to consider the GEN2?
