Lets see...
=COOP=
LIKE: GFZ2
Why: All-time favorite with an inviting atmosphere, great music, and a great sense of exploration and freedom. Looking down upon the lakes and fields from atop the huge mountains will always be a reason to keep going back to it. Arid Canyon's a very close one, but relies a but too much on the "choose your pathway" principe, where all the paths come to the same point multiple times throughout the level.
--------
HATE: DSZ(In general)
Why: It's boring, colorless, bland, slow, and the gimmicks are way too strict. You have to stop to do the boring gimmick everytime with hardly much ongoing pace in it, let alone action. It especially gets repetive fast, and personally, I wouldn't take the time to explore the place more either. You take both paths once and you've seen everything you wanted to see. Rather collect the lives and rings at Arid Canyon or Greenflower, it's actually fun there.You can hardly backtrack as well. It's a well known fact that nobody likes water stages in general, there's only few exceptions to that.
=Match=
LIKE: Meadow Match
Why: I dunno, most people'd say it's bland and boring, guess it's just me. I'm just happy to see an open big stage for once where you can all out, rather than all these filled to the brim stages with an overdue of random hills, obstacles and stuff. Or where you have to worry about every single wall and corner.
--------
HATE: Infernal Cave
Why: It's cramped, has a strong camouflaging theme to it, it's filled with random invisible flamethrowers that even hurt freaking Super Sonic, you worry more about the random crap and lava around you than your performance, and you can't go all out with your speed.
=CTF=
LIKE: Lime Forest
Why: The principe's just as repeat-possible as can be. Lots of basic tactics that can be taken to an advanced level in this map. Though I'm no fan of the new textures, I mostly really wish the middle field/lake was a bit wider.
--------
HATE: Teh Nimbus Mapz that somehow made it all the way to here.
Why: I think this map wasn't tested online. If it was, they'd have noticed it's as good as unplayable with any lag but 3 percent lag or below. It's also annoying with the new 2.0 weapon system that nearly all the weapons blow you further away, you nearly ALWAYS get blown off the stage when you get hit, losing all your weapons and all you have. Also.......aiming+shooting+speed+platforming+lag = Syntax Error, so nearly everyone always switches to Tails here, where they're usually Sonic or Knuckles. At that, most of the item monitor placement is just bad. You'll always get a railer going at you if you stop or slow down even slightly for one since you can't spindash here against it. Finally, in the stage it's hard to get rings, and even more now since the dumb idea of team rings, and the only relief of infinity ring back then.
=RACE=
LIKE: Toxic Citadel
Why: It's a straight forward race map, one that doesn't make you slow down or have to use small thoks, yet you still have to watch out with the timing and curves, keeping skill present. The speed is also quite noticeable with all the not-slowing gaps of toxic and the stair things at the beginning.
---------
HATE: Emerald Coast
Why: Hard to say, it just doesn't play good. The heights of the hills, the timing in the curves, the distances of the paths, the lot apearing differences between cramped and open areas, and the bad indication of where to go. It's really hard to just speed fluently through it without annoyances.
