C'mon... that is really apples and oranges. Cheaha is super fun for different reasons, and Lake Howard is also super fun - for different reasons. each trail is COMPLETELY different.
my answer to the first question posed on this thread: go ride every trail you can in your local area, and then go ride elsewhere. the only way to become a more proficient rider is to go ride other places. try anything once - it may or may not be for you, but you'll have an opportunity to maybe learn new skills, or not.
there is no better or more exciting feeling (to me) than "sight reading" a trail for the first time. the music analogy is quite good here - you only get 1 shot to ride a line the first time.
