Played borderlands through endgame and I can say conclusively that destiny is better by a wide margin. It's not that borderlands is bad. It's not. It's a good game. Put it this way. I bought borderlands knowing it would fill the 2 weeks before shadowkeep and expecting it to overlap. One week after borderlands launched, I was max level, had pretty much every legendary and no vault space left(despite it being maxed out) to get any more. There was no content I hadn't done and no reason to do anything again. One week after borderlands dropped, I was back on destiny 2, 2years after its release and 3.5 months after its most recent content drop, with a ton of stuff still to do. The quality of the content is better. There's more to do. The content has actual exclusive rewards. The quality of the gameplay/gunplay is better. To be fair, it's slightly disingenuous to compare them because, while they're both looter shooters, they tackle the genre in very different ways. Borderlands is more campaign oriented and destiny is endgame oriented. Borderlands rains loot while destiny makes you earn it but that makes the feeling of getting a yellow in BL about as special as getting a purple in destiny. None of the content in BL3 is remotely aspirational, which is on account of it being campaign-centric and not focused on endgame.
