What makes a coaster great is so personally subjective it's very difficult to come to a general consensus. Especially when it comes to central Florida with the likes of highly themed coasters in WDW and UO vs. just bare bones hyper thrill coasters, and everything in between where an attraction might be on coaster tracks, but is more perhaps something altogether unique.
This is what I love about Universal/IOA though that I feel sets it apart from other Theme Park and standard Amusement Parks. It has some of everything across all potential coaster classifications.
Type A - Standard pure "High thrill" coasters (non-themed or only mildly themed):
- Hulk
- RRR
- Previously Dragon Challenge, but eventually we will get this JP coaster
Type B - Ultra Themed Coasters:
Type C - On Coaster Tracks, but an entirely different immersive type experience (so may not even be classified as a coaster):
Type D - Low Themed pure Kids Coasters
- Hippogriff
- Woddy's Nuthouse Coaster
IMO WDW severely lacks in Type A's and regional Amusement Parks (Six Flags, Cedar Fair, Busch Gardens etc.) severely lack in Types B and C. Universal has the best mix of all of them (and I'm sure we'll continue to get an above mix with the new park too).
