I had a 5D II and used one of those screens. It helps, slightly, but not for critical pin-the-focus-on-a-gnats-butt focusing. So, whether shooting with a 5D II (previously) or 5D III (now) I use the camera's focus alert system, which is good for 85% of the time. What I use now is a Zacuto Z-Finder which lets me use the full power of the Live View system as a sort of EVF hack. This is what's so nice about the A7R: It has an excellent EVF built in. And, from user accounts, it doesn't have the same lagginess that the Canon Live View system has.
When considering the A7Rs EVF system, the difference between the 6D/ 5D II and the 5D III for manual focusing is negligible from a MF standpoint. I still need a great AF camera for my two excellent AF lenses...the 1DX was a recent addition, which now permits me to consider selling the 5D III in favor of an A7R (I plan to sell one of them...but not 100% sure which one I prefer to keep.
Whatever works for you. I've heard at least one other member say they didn't see much difference with an EG-S screen too, for me the difference was huge though... idk, maybe difference in perscriptions? All I know is that the EG-S screen was the best thing to happen to my shooting experience, I actually prefer MF lenses for what I shoot most of the time and thankfully haven't had any issues catching focus with the 6D
The biggest draw of the a7 for me is definitely it's form factor, but I'm really turned off by the super loud shutter (even though it's hard to get a real idea of it's volume from videos).

Question for those considering the A7R... for a AF shooter is this a good option?
Ill be honest Ill buy stuff that I do not need just because its better.
There is a lot of hype behind this camera.... Give the slow AF with the adapters but with native lenses is this a promising solution or Sony's flavor of the month?
It's going to be significantly slower than your 6D. With the native lenses it should be about as quick as the 6D, but for moving subjects it probably won't be ideal if it's anything like other mirrorless cameras. Whether it's "better" is subjective. It's better at some things and worse at others, it really depends on your needs.
If I had the money I'd definitely pick one up as my secondary backup camera.
