They are diff games, I cant say much about black desert cuz they IP blocked me so ya, but graphic looks amazing, other than that I don’t know, people says combat boring but then again I cant agree cuz I didn’t try it and I probably will never try it since the IP block.
Blade and soul, yes it been out for years, but for many people the hype didn’t die yet, I see some complain but well… people complain about everything So…
For me, I’m enjoying the graphic, combat, pvp/pve, costumes, lore is boring but who cares xD
ToS well ill make it short and say that i just love it.
So… ill play both, blade and soul AND ToS 
And archeage… since people talking about it, for me, i had a lot of hype, but what killed it for me and many other people is the bots, P2W, RNG… (250$ on Pegasus and never got it…-cries- Lol)
But anyways… You shouldn’t be worried i guess.
