Coincident S E III vs Total E

I own S E III's and like them, but I thinking about maybe upgrading. I read all the reviews and emailed Mr. Blume and really can not decide. Any input would be appreciated.
bigger sense of scale with the TE's, more effortless on the deep bass as well. It also depends largely on room size. I used to own SE's, and skipped the TE's in favour of the TV's, but would be happy with any of the above.
