The rating aren't comparable between Alafia and Balm and many disagree with which deserve what (IE, I think Magic Island and Twister Sister are black, but they are officially Blue). Either way, it seems you are looking for opinions, so here is how I'd rate the difficulty of trails in those two systems:
Hardest to easiest:
Moonscape
Gatorback
Frank's loop
Pandemonium (if you keep right)
North Abyss
Ridgeline
South Abyss
Shelly's loop
Derailed
3rd hard option Rollercoaster
Rabbit ears (3,2,1)
OAF
Hard option at the end of Bridges
Razorback
First hard option on North Creek (that most don't even release has a bypass)
Twisted Sister
Magic Island
2nd hard option on Rollercoaster
Buzzard Bay
Rock Ridge
And by hard, I mean difficult to ride without dabbing, stopping to take a breath or just all around scary (IE, Moosncape is the top because of the part where you have to ride up the side of the hill, make a hairpin and come straight back down).
