Might be a few years late for this but

I remember being into BTDBattles on my mobile in middle school, played it for a few months and dropped it.

I wanna get into it again, but now with the release of Battles 2 and its.. fairly "mixed" reputation I'm unsure of whether I should go back to the first one or just jump into the sequel.

I do plan to try out BTD6 eventually as well.
