BD/SP. Its not because of the graphics or other similar arguments, its because ILCA (not Gamefreak), kept a lot of things that hindered QoL for players, especially when it came to breeding and hidden abilities...which I do most of the time. That's how I got 999.59 hours in Sword. 200 BP for HAs??? I'd rather breed in Sword and send over mons thru Home than go through the grind of the Battle Tower. The Pokeradar doesnt work in caves or with mons in water. There are so many limitations that it can just get frustrating. Breeding is also better in Sword. You get a bike sim route thats longer, two breeding facilities and high IV Dittos thru a Isle of Armor den. I've actually started to breed BD/SP mons in Sword now just send over to BD once its Home compatible.
