Got it on my S3 (is it ok to talk about it here?).
Well, I think the first one is much much better, it only has improved on graphic, no big deal.
In the first one you COULD get better, the generated levels rarely punished you with an unreasonable series of obstacles to overcome, unlike this one. You could die after the 2nd/3rd turn just because the level has generated a wall you need to jump just after the turn. What's the meaning of this? No matter how much you're good, you'll be screwed if the game decides so.
Powering everything up is a pain in the ass because it takes really a lot of coins. The soft turns (the ones you don't need to do because it's just the road curving) only serve to hide part of the visuals, forcing you to do a last-second slide to avoid obstacles/falling off.
In the cart sections often you have to gave up to the idea of collecting coins since if you have to lean for it you need to take into account that after a turn of the road there could be an intersection where you need to lean the opposite way, and there simply isn't enough time for the cart to get back on track and turn.
And even if you get better and manage to make a jump right after a turn you could incur in a bug (or at least I think it's a bug) where your character jumps and yet it falls dying (you can notice because basically your character jumps towads the left or the right in an awkward way).
So basically I think the game is crap, except graphic-wise.
