I also feel like, generally, the maps are more interesting. Being on the dealing end of this feels amazing.
The combat also has this oomph because of how dangerous the weapons are. I definitely have the least experience here, so I cant go into too much detail about how the endgame or p2w aspects are. You also have to like ships combat, something that I think isn't as universally enjoyed as tanks or planes. On the downside, the game is very monotonous (to me) and WG's greed is more egregious here. It also generally has the easiest progression.
Warships is relaxing and has the easiest newbie experience.
