*nod nod* As someone else said elsewhere, BDO does have open world PvP past a certain level (in this case, it's level 40, though there's a quest to allow level 35's to also participate).
It depends on your personal preferences and tolerances. If you tend to like RPing in city areas and housing, you'll be fine in BDO without worrying for random PvP, since they're safe zones. If you particularly like housing, Black Desert is the only one of the two with housing in it (and it's a really cool system too). In my experience on PvP servers, I've rarely had much issue with RPing, especially in out-of-the-way locales -- so for me, the rare annoying occurrence isn't enough to cause an issue, especially when I enjoy the gameplay, the graphics and the atmosphere.
