Which one takes better pictures?



OK, this isn't one of those threads. The question is, do you have nice efs glass for your crop bodies or try to make the whole kit interchangeable?
I just bought a 60d a few minutes ago. My plan is to likely go 6d (pending real world issues) after the price takes a hit from the initial opening. I am finally moving on from my xsi(loved it), and my new gameplan is to have the 60d for kids sports, surf pics etc. and the 6d for work shots(interiors) portraiture, low light, and everything ff is awesome at.
So far the plan sounds good. I currently own a 17-50 sigma and a 10-20 sigma as well as the 100-300 f4 sigma (great copies of ALL and I am a huge sigma fan as a result) and then some crappier lenses I will sell off or give to wife with xsi. I will probably get the 17-40 (for work) for the 6d when i get it and then add primes as I can afford to. The 100-300 is a full frame lens, but the wigma and the 17-50 obviously are not. Should I keep them for use on the 60d, or sell them ($750 realistically) and just add a few hundred for good ef glass.
I feel I am currently inclined to save them, and make the 60d the camera that I leave in my truck for the you never know stuff and have it all covered. I am thinking that is probably worth more to me than the $800 towards a prime and a slow 17-40 on a crop when I am used to an awesome 17-50 2.8 that is probably a much better lens on a crop.
What do you guys do?
In the mean time I plan on enjoying my lenses and new body so no rush I guess to come to any conclusion.
I don't own full frame except for a film camera, but until relatively recently I'd been harboring the idea of going full frame at some point. I've since ditched the idea because I can't see getting so much more out of full frame than I get out of my 7D that it would be worth the expense of owning two formats.
In any case, what this means is that I have a few full frame lenses, e.g. the 24-105L and the 70-300, so I do have some choice as to what lenses to use with my 7D.
If I had both formats, I'd still keep the crop-specific lenses because it's really the lens that makes the biggest difference in terms of the quality of the image you get and the suitability of the camera for the task at hand. I'd much rather have a little more invested in lenses so as to ensure that I've got the right one for the job than to compromise on what is, for photography gear, the most important piece of the package.
But that doesn't mean you should keep all your crop-only lenses. Instead, you should keep the ones that are of greatest use to you. If you use your full frame camera for wide angle shots (where, frankly, it excels, especially if you need subject isolation at the same time), then the only reason to retain wide angle capability with your crop camera is if you intend to use it as a backup. Otherwise, you may as well sell your 10-20. The 17-50, on the other hand, is so useful and versatile that I'd be inclined to keep it because it means that your crop camera will be able to act as a backup camera for most situations.
I would get the full frame camera first and see how you wind up using it versus your 60D. That experience will tell you what crop-only lenses to sell.
