I own the TM P90 with 2 gearboxes completely stock, the other highly upgraded for field use. The gun was purchased used from this forum and supposedly run hard for 4 years and now i've had a chance to run the gun now for 1.5 years and not had any issues. My experience with the stock gearbox is excellent. Once you put upgrades into the guns you can't really make fair comparisons.

I haven't worked on a CA90 but I have heard positive and negative about it from forums. The only consistently bad thing I hear about the TM P90 is that it's "low FPS".

I'm part of a Chinese language airsoft forum for Mainland China players and THEIR preferred P90 is the TM over the CA, JG/echo because of the superior hopup from the TM model, & that the gearbox shell is very consistently built.
