Hmm, this is actually a tough one. I haven't really been a prominent designer since the ages before Elementary and heartlining, so most of my famous tracks are a bit overrated, and I really don't like them much anymore, but here goes anyway.
1.
Hydro Thunder
Although I really wish I'd added more variety to this coaster, it's definitely the most complete coaster I've done as far as the pacing and the setup, so I consider it my best.
2.
Volare
This coaster wasn't rated as high as my other tops, but I feel like this track is the most fun to ride. That reverse fall out of the station is my favorite part of any of my current coasters.
3.
Meteora
I'm still proud of that drop off the MCBR, and I love the adrenaline that this coaster ended up with despite how I had to sacrifice a bit of the randomness because of my old building technique.
4.
Cataclysm
This coaster started with a great idea, and the raters thought that it was great, but I personally have always been disappointed with this coaster. The pacing in the middle really dragged, and there wasn't enough falling on that first drop IMO. I give it 4th because it's my most famous coaster, but I'm actually making a version 2 because I hate how overrated this coaster is.
5.
Vertical Xtreme
This coaster is a bit primitive by today's standards, but I included it because it was my best coaster from the 'old days', the 2003's, when I made a different coaster every week, everyone knew me, and annoyed the hell out of everyone with my endless advertising.
