I love the atmosphere at a BJJ gym. It's not that I have a problem with all the bowing and Japanese terminology in Judo, but I love the culture at a BJJ gym where everything is just so chill. We still train hard and there's plenty of respect, but none of it is forced.
I also love how BJJ, compared to other styles, has a ridiculous amount of training resources. Online there's great blogs like BJJWEEKLY and AESOPIAN, on youtube there's channels like Trumpetdan, and new books are constantly coming out from the sports best competitors. Try as I might I can't find that same breadth of resources for judo or any other style.
Lastly, BJJ competition rules make sense and there are less of them. The competition rules of Judo seem to change every few years and it's usually in the direction of limiting techniques (leg grabs, for example). BJJ hasn't gone in that direction (so far anyways) and we also do no gi. There's greater opportunities to try new techniques and strategies under such a broad rule set for grappling.
