Subnautica vs Subnautica below zero -- is Subnautica better?

[Old Man]

I've just completed Below Zero (again) and thinking of installing Subnautica for another play as it's been a long time, so wondering what you all
think of the first game vs the second? Also, there's a mod coming out early 2023 (hopefully) -- "Gargantuan Leviathan Mod, which should add a bit of
more fun .

TY

Thanks all.

I'll be playing it again and I did ask because my internet connection is rather poor right now, so even the 5gb dl is going to hurt some.
