Coolbeans, have you been on Manta? If you ride it then Tatsu feels like a kiddie coaster (except for the Prezel Loops, they are the only comparable elements).
I'm one of the few members on this site that has been on both. I have been in the last row of Tatsu. Tatsu's pretzel loop is not as forceful as Manta's. Manta is more aesthetically pleasing to the riders and viewers in terms of scenery and layout. Tatsu offers great views over the park but appears out of place.
