The quality of Epiphone Dots cannot in my opinion be overstated, especially for the price.
The differences between it and the Sheraton are relatively minor, other than "bling" factor. It should all come down to which neck feels better, individual resale value and which looks cooler to you. Well, there is a slight tonal difference due to neck material/construction, but it's not immense.

After various easy and inexpensive upgrades and customizations there is no way I'll ever get rid of it. It sounds amazing and I prefer it's understated look to the Sheraton's bling factor.
Even without upgrades, the Dot is a great guitar. Here's some proof...
