My relationship with the series so far:
Borderlands — came for fancy graphics, didn't stick for too long
Borderlands 2 — came for guns, stayed for junny jokes
Borderlands 3 — came for jokes, stayed for guns.
I mean, BL3 has much, much more improved guns, and not just shooting is fun, but guns themselves are. I played BL2 year ago and I remember lots of boring guns, feels like devs were trying too hard making them not just the usual shooty thing. In BL3 I can have actual good assault rifles that are unique, punchy and fun to use.
