No the verdict is not in, and here's why:
Every time I think: is sr8t razor shaving really better then cartridge shaving in terms of a close shave. SO, I say to myself, next time I shave, I'll use my Gillette Mach 3 and see because its been so long since I used it, I forgot.
BUT, when the time comes, who the &%$#& wants to shave with a mach 3, I wanna use my sr8t. So, there you go, I'll never know...
