while not a Type R, I have an old 1997 integra and the difference between the Integra and the Euro is pretty huge. While certainly not the quietest car around, the Euro feels like you're driving around in a bunch of leather covered pillows all wrapped up in concrete compared to the Integra. Jumping back into the Integra it feels like a go-kart with windows....you can see all around easily (a bit of a problem with the Euro, especially the A pillar), it feels tiny inside (Euro is wide but a bit short of legroom in the back). The clutch in my Euro is much stiffer than the Integra, the gearchange in the Integra is much more mechanical and direct feeling than the let-me-help-you-with-that gear change of the manual Euro. The gear spacing from 1 to 2 in the euro is a bit crap. Standard suspension dives much more under brakes in the Euro. There's a lot more torque in the Euro and it doesn't feel like it's travelling as fast as it really is.

My Integra isn't a Type R so the differences between a DC2R and a Euro will feel slightly more extreme than what I get now. I generally prefer driving my Euro as it's just easier and less work. If you can, have the two at once and then if you need the DC2R, then keep it. I bought my Euro for it's four doors (i.e. baby!) and I'm selling the Integra but circumstances might change for work and if I have to start driving to work I'll need two cars!
