I was in your position and unsure as to what to get when my GTI PP lease was coming to an end. Did I go for another PP or get an R? Then the TCR popped back on my radar and well thats where I went. I've not got DCC, really doesn't need it, even on 19's though appreciate some like a floaty ride, in which case DCC in comfort will likely sort you out but without its plenty compliant whilst not rolling all the time. Didn't feel much difference switching from the 18's it came with to aftermarket Ultraleggara's either. I also love the fact that you just don't see them about much, I know there are around 3 or so in a 30 mile radius of me, I've never seen one on the road at all, certainly not in the only colour I'd have ever chosen, the grey.
Price as always comes into things, PP's are cheap enough and over time and spend money you could get it close to a TCR (kind of), R's are good to go but a bit safe and boring (and everyone has one), TCR's are in essence a limited edition 2wd R and are amazing to drive.
If you can afford one, go for it, a lot have mileage on them appropriate for the year, I was lucky and got one with 6k on it for similar prices to the 15+ k mileage cars out there and was pretty much pristeen. You'd not regret it, especially if you're looking to keep for a fair while like I am.
