First of all, thanks for pointing out some very valid points. I even decided to get a lens or two before diving in.
I have a few lenses that I think can get the job done. But mostly they may not be the top level lenses I would love to have. I think it would be good to see how the perform on a full frame camera, though. I have EF 50mm f/1.8, Vivitar AF 100mm f/3.5 Macro, Tamron AF SP 180mm f/3.5 Macro, EF 28-135mm f/3.5-5.6 USM IS**, and EF 70-200 f/4 L USM IS***
**Perhaps not super fast, but it seems like a good performer. I picked it up for $40, and was pleasantly surprised.
***On order, express delivery. I like the size and the price much better than the f/2.8 version.
I don't plan on doing a ton of portraits, but my impression is that the IQ improvement is in the format, not the lens, meaning (and I could be wrong) a portrait taken with the EF 70-200 f/4 L @ 100mm taken with the 70D will not be able to compare to the same lens with the 6D at 160mm. I may be totally wrong about this, but it is just a new thing I'd like to explore.
No way would I say the 70D is letting me down. I've taken portraits with the EF-s 60mm f/2.8 USM Macro and they are very decent. I also recently bought the EF-s 10-18mm. It is an awesome lens and almost satisfies the need for wide angle shots. I though it would quench that thirst, but instead it makes me want to see how it stacks up to my antiquated Tamron SP 17mm f/3.5 Adaptall-2 lens. And sort of makes me want to look at the Samyang 14mm f/2.8 on the 6D.
There is a thing that interests me. Mostly because new lenses are so expensive, and when I started photography ten years ago it was easy to get good results with MF lenses, I bought up quite a few old MF lenses when I came across them and the were cheap or free. I have to say I can no longer get consistent results with them. But occasionally the results are outstanding. I suspect that the 70D is much more dependent on whatever electronic data modern lenses provide. Or...Can a full frame do a better job with handling exposure consistently? If not, it pretty much marks the end of a long era of getting unique abilities of old Nikon, Pentax, Olympus, Tamron Adaptall-2, Sigma, and miscellaneous other old legacy lenses. Honestly the results always were inconsistent, but for a three year period I used the MF Tamron Adaptall-2 35-80mm f/2.8-3.8 Macro because it was better than the two kit lenses that came with my T1i. And unlike many people I think very highly of the two kit lenses. Even more so of the STM versions that came with the 70D.
Maybe the quality of the MF lenses doesn't stand up to the higher resolution sensor, or maybe I have lost the touch. It would be interesting to see. Despite the fact that people don't talk about it, I have to believe that the larger image circle of the 35mm lenses must cause a lot of problems due to stray light bouncing around, probably lowering contrast.
So, you see, I have a lot of curiosity about the 35mm format. And I don't think they can be settled without having two comparable quality DSLR's. I might end up hating the 6D because of my leanings towards Macro and Telephoto work. But 10 years of wondering can drive a person crazy!
