Why do my TPU prints look like this?

First time printing with TPU. Another problem I had was that it didn't stick to the textured print bed, had to go for smooth PEI which I read (and now can confirm) is not ideal. Would satin be better?

I had similar messy results at one point -- it tuned out to be a bad zOffset. Having said that, my part also as a messy top layer -- not sure if yours has that or not with the little nub there.
- No, that nub is not on the head, it's slightly beyond, this is due to the angle. The z offset works for PLA, I assume I don't have to change it for TPU?
  
  Yeah. If you are good for pla, it's not likely the cause.
