I agree but with that said the GearVR lens mod really does work well on both devices. They go from absolute rubbish lenses: blurry, low sweet spot with ring artifacts to crystal clear with very minimal god rays (hardly, if at all noticable). It is quite an upgrade.
How long did it take you to dial out the distortion on the Pro ?
I did the mod last night and uploaded grodenglaive profiles (tried 14/24/25) but the distortion was still pretty bad.
I figure that i will need to dial them in from scratch using the steam-vr-undistort tool that sencercoltu wrote.
Switched back to the fresnels for now [blah]
