Which half of Sonic 3 is better?

[AngryNerds100]

I personally think that Sonic & Knuckles is better.

I like the first half's level design and music but the second have had hyper sonic and Sky Sanctuary!

I think Sonic 3 is better because it seems i had more fond memories of it when i was younger
