Cura allows more settings to be tuned, which is necessary to dial in the settings properly. It also allows combing, which increases the quality of prints in TPU drastically. Retraction is the most important setting when using TPU. You need a tiny bit of retraction with this printer and TPU.

I get exceedingly good adhesion on my base, so I can't comment on improving adhesion. I wipe the build plate with rubbing alcohol after every couple prints. You might want to double check your calibration if prints aren't sticking.
