SOLO is definitely not known as the "next big thing" to most players afaik, but for the ones who are enjoying the game, it sure is. There was never any major hype or major marketing around it even to this day. Personally I think it's great and super refreshing. I enjoy the world, the graphics, character creation, movement, combat, etc.
Lost Ark however -is- being marketed as the "next big thing". It's also known for already being p2w. Whereas SOLO is not and that is a huge positive. Also, Lost Ark is obviously going to be different than other most MMORPGs, even with the official website claiming it is an MMOARPG. So naturally, it would have more playability than most other MMORPGs. It's more similar to Diablo from what I understand, with more MMO elements.
If Lost Ark is the type of game that you prefer, that's good for you. But it's not a fair comparison in the way you're doing it.
As comparing SOLO to FFXIV, I'm glad SOLO is not like that game. It makes me drowsy when I've played it because it's so dull. Sure there's replayability, but it's all the same and mostly no challenge. The story is also incredibly mind numbing. The character creation is also terrible.
As for Black Desert, I don't have much to say other than why would you want to be afk all day in order to progress?...
To each his or her own, you know.
