6se vs 8se vs c6 sgt

First, none of the scopes you listed will exceed what the Xt10 could see. With 10 inches of aperture it gathers more light and can pick up dimmer objects than either the 6 or 8" SCTs. The 8SE would be the closest to it in terms of visual usage.
If you want to take images and are not too serious about it, any of the scopes you list will do fine. You'll be able to take images of brighter targets like the moon and planets, and some of the brightest DSOs like the Orion Nebual and the Ring nebula.
If you want to take longer exposures of dimmer DSOs, you'll need a GEM mount. The CG-5 mount that comes with the C6SGT is an entry level mount capable of longer exposure astrophotography (AP), while the 6SE and 8SE are not.
So, if you want the scope that comes closes to the Xt10, and you want to do primarily visual and maybe dabble a bit in AP, then the 8SE would be a good choice. If you think you might get a bit more serious about AP in the future, then the C6SGT is the best choice. But keep in mind that the 6" scope will be a big step down from the 10" in what you can see with it.

I have the iEQ45 GEM mount for astrophotography, and the SE mount for visual use. The iEQ45 is a wonderful, solid, accurate mount and I love it for AP. BUT ... when I just want to go out and look at the sky with my own two eyes, it is too heavy, complicated and too time consuming to get set up and align. The SE mount, on the other hand, is wonderfully light weight and simple to use.
Having both mounts is the best of both worlds!

I still starhop as my other Scopes don't have such mounts and I still value those navigational exercises but all the same I'm a GOTO proponent something I swore could never happen.
At anyrate the user functionality of an 8" GOTO could very well let you forget the 10". Too, those XLT coatings really truly provide impressive light throughput. It is a little more than the 6" but I really am very very confident this is a desicion you won't regret.
