I think I can give you a personal insight since I recently traded in a DGT for a CU24 for purely personal reasons.
I owned my DGT for about 18 months, it was my first PRS, and I originally bought it as I was looking for something between a strat and a les paul. I'm a strat player historically, and I liked the DGT's McCarty roots, and the quality of the instrument as a whole. It seemed like the DGT was the perfect guitar to step into humbucker/mahogany territory. And it is, the DGT is a wonderful instrument, perfect by design for it's niche (and that's a large niche).
So why did I trade it? Again, for purely personal reasons. After playing the DGT, when I'd pick up my strat I'd notice few things. How much lighter it was, the more bell like high end, the smaller neck fitting my hand a bit better, and just being more natural for me to play as a whole. I still wanted the DGT's tone and sustain, but it was just a little too dark by comparison. The DGT's pickup's are clean to about 7.5 on the volume control, after which they began to sizzle. Now that's perfect for some people, but I missed my bright clean tones.
So one day I spotted a beautiful 30th anniversary azul CU24 in my local music shop and I picked it up. Everything I wanted from the DGT fell into place. The slimmer body was lighter, more comfortable and more balanced. With less mahogany in the back I noticed the tone was a bit lighter and brighter, not as thick, but still substantially more so than a strat. The neck was a pattern thin, which i now realise is the perfect neck for me. The DGT has a fuller neck profile, and while it's still very comfortable, the pattern thin is just more suitable to a smaller built, smaller handed guy like myself.
The 85/15 pickups are warm, but they don't sizzle like the DGT's. The final clinch for me was returning to the 5 way pickup switch. It's so versatile I use all the positions regularly, and while the DGT has an awesome coil-tap, the 2 and 4 positions on the CU24 can do things that the DGT never will, and as a strat guy, that really meant something for me. Also, I prefer the neck pickup on the CU24 being further south, I think it balances the tone better.
So that's it really, I hope this helps you in your decision, let me be clear that I'm not disparaging the DGT in any way, it will be a perfect guitar for many people, but the CU24 is just better for me.
Good luck with whatever you choose, and be sure to post it here when you pick one up!
