BDO vs. OSRS - Help me pick what game to play!

So I wan't to either start playing Black Desert Online or Old School Runescape again.

Both are grindy games but BDO is more R.N.G based.. but combat is amazing. A lot of things to do/interact. Very realistic game, feels very satisfying to progress. Fairly new, don't know much about end-game.

OSRS is also a grind-fest, but i've played since my childhood, & have some Wealth + Knowledge. I love the PvP & PvE in OSRS but grinding in this game is extremely boring/afk a lot.

When i think about doing quests and farming up to get gear to do bossing it just feels so nostalgic. Eventually getting your preferred PvP spec weapon ( ags, claws ) and just recking ppl in the wild.

What do you recommend ? (fkleaguebtw)
