I could not even tell the difference between both games' tick rates :P
While I love Splatoon 1, I prefer Splatoon 2. More variable weapons, more stages, Clam Blitz is really fun, Salmon Run is awesome (even if I get my @$% handed to me at times), and the single player has more variety in terms of gameplay and weaponry. Plus, the Octo Expansion is primed to create even more great single player content.
Though I do give the nod to Splatoon 1 in terms of music. I can never get some of those tunes out of my mind and I think the original main theme is better than Splatoon 2's, though that's not to say that 2's main theme is bad in any way. Plus the final boss in single player was epic.
