I have tartan and DCC on the GTD.
Have previously driven 2 BMWs and 2 Mercs with leather and have not missed at all. I don't have kids or allow people to eat hot, messy food in the car, so I guess that helps. The material is also good and despite nearly a year of the local car wash boys using vacs on it, it remains like new.
I would chose DCC again, Sport mode is great for a fun B road session, but too firm all the time, comfort is great for motorways and rough track roads where I live but a bit fluffy for a fast drive on varied roads , but to me the choice of both plus the "normal" in between setting is money well spent. I have the car for 2 years, so it works out less than £8 a week, so for two pints of beer - well worth it.
