06 and Labyrinth were SUPER close together. Out of all the games, I gave Labyrinth a 1/10 in controls, and it's the ONLY game to get 1/10 for the controls category, because it spits on Sonic's niche of being very speedy...
but it functions better than 06. While 06 has excellent music and Sonic actually goes fast overall, it does everything else VERY wrong. 06 is a broken mess, Labyrinth is infuriating but it's slightly less broken than 06.
I've heard the Saturn version is significantly better, but I've never played it. I do love the Panic Puppet theme from the Saturn version though...one of my favorite Sonic songs because it's so bloody threatening and adrenaline rushing...perfect for a final level. Was also used in the fan game called Sonic Dimensions, which is basically 2D Unleashed but with excellent physics...and it's amazing.
