For me it's a toss between Shearwater and the Heinrichs Weihkamp (OSTC) computers. I own both, recently switched to a Perdix AI because the OSTC2 TR (AI model) failed to deliver reliable AI. Display on the OSTCs is better (bonded display, unlike the Perdix, so much higher viewing angle. Not a huge deal in practice, but noticable).
With the straps the Perdix is more comfy to wear on the wrist, with bungees the OSTCs are better. For some reason haven't found a way to make bungees comfortable on the Perdix.
