I'm a retired industrial designer and bought my first RAM ('15 2500) because it had the best styling of anything on the market at the time, IMO. I had planned to keep the '15 longer, but the spike in used truck prices prompted me to sell it, and I went back to the well for another 4th-gen, as I don't care for the 5th-gen styling as much.
The DS has been on the market nine model years now, which means it's not only well-sorted (for a FCA/Stellantis product), but has a well-established and deep aftermarket. As others mentioned, the downside if you want to stand out, you're competing with a very large number of DS trucks out there.
How much you end up 'standing out' really only boils down to your imagination and budget. Plenty of ideas on this site and all over the interwebs, so make a list of different mod options, put together a combo that works for you, then do it!
