In my experience, most dedicated 35mm give more detail, but they give you a "dry" almost harsh gritty look. The Epson flatbed scanners don't give the same level of detail, but will give you a much smoother "wet" look. With careful scanning and careful editing and the right amount of sharpening, I've found that I can usually get better looking results from my V750 than I can get with my Nikon Coolscan V.
I have a 4990, which was the immediate predecessor to the V750. Forget about the exaggerated resolution claims that Epson (and others) tout regarding their flatbed scanners. Mine supposedly has 4800x9600 dpi resolution with a 4.0 DMax. Even though it did a decent job of scanning negatives and slides, I was never quite happy with it because I could tell, just by looking through a loupe, that the 4990 was not generating the sort of resolution I was seeing with my loupe. After doing quite a bit of research on the subject, I found out that the 4990's real resolution is something like 2000 pixels per inch and that the V750's is only about 2200 to 2300 ppi.
But one thing I did find that sort of blurred these values was, if I scanned at maximum resolution, the gradient in colors that was recorded was quite a bit finer than the resolution the printer was supposedly recording. So, suddenly it was no longer clear what actual resolution was anymore once the gradation of colors got tossed into the mix. I suppose if I want to look at edge definition, I need to use the lower resolution number, but if I'm looking at color depth, I need to be aware of a noticeably higher number. Perhaps this contributes to the "wet" look you mention, since there is a noticeably smoother flow of color at higher scanner resolutions.
These days, I use my 4990 for medium format scanning, which it does an excellent job at, and I duplicate my 35mm negatives and slides with my 24.3 mp Sony NEX 7. 24.3 mp gives me 4000 x 6000 pixel images. I find the reproductions using my duplication setup to be very faithful to the originals.
