If it wasn't for the Gen 4 I would've never gotten into Glock...I'm just not a fan of the Gen 3 at all and don't have any desire for the 5th generation. However, I'd end up having to rent a few, but I have a feeling I might would land in the M&P realm. I just tend to lean towards more common guns. The CZ and FN 509 family look appealing though.
