Mute City.

Seems the crew having more experience now than when they made the original tracks has paid off; the next DLC pack should look amazing.

Definitely Mute City! Dragon Driftway comes in close second!

Dragon Driftway for sure. For some reason I notice a lot of jaggies when playing Mute City. I think there's just so much going on, maybe a bit too much for the Wii U...

To me, it's between Dragon Driftway and Hyrule Circuit. None of the others come close to looking as good as those two (not that any look bad, but those two exemplify Nintendo's visual design skills more than the others do).

Its more a matter of a visual design; lots of narrow, high contrast lines and edges just makes them stand out more.

In terms of prettiness, it's got to be Dragon Driftway. It's just so rich in colour and effects, and is the only track in the DLC pack where the looks and design wows me more than the racing experience. (not to say that the racing experience is bad, that's awesome too, but I feel like I choose that circuit more for the sight-seeing than the racing) My favourite turn is the left turn where you have the rising (setting?) sun glaring and reflecting on the track, making the glow of the boosts in the centre line more of a challenge to see. I think it's great that Gobblegut from Galaxy 2 features as the dragon.

Mute City is a close second for me. I like how they have the laser MarioKart and F-Zero letters going across the start/finish line, and the details of the city in the background give a real sense of size and height - moreso than the various Rainbow Roads. Of all the tracks in the DLC pack one, Mute City is the only one where I couldn't choose whether the prettiness or the racing experience is better. To me they're equal, and that makes Mute City my personal overall favourite track.

Most definitely. They're making the most of the antigrav mechanics - narrower tracks and carefully positioned boosts mean racers are more likely to bump and boost one another - makes for very satifying racing. And Mute City is 100% antigrav - I love that jump where you're basically in freefall for a couple of seconds, and can even steer a little bit in the air as if you had a glider. There's more of a feel of racing sideways or upside-down, as well.

Next iteration of MK to include Galaxy-gravity style space-racing maybe?

This DLC pack is amazing. Loved all the tracks.

While i enjoyed driving in Mute City and Excite bike more, Dragon Drifway is the prettiest. Ice Ice Outpost is also amazing.

Easily Mute City..  Dragon Driftway is also pretty nice-looking, but Mute City takes the crown!
