Hey bud,
Both are good cars, if your going to get an EVO 6, try go for the better speced Tommy Makinen Edition, you say you'll keep them stock so ill assume they're not going to see much track time, EVO's are really focused and purpose built, very stiff and firm to drive but a real drivers car.
The DC5 is also focused but not as much as the EVO, great cars for the street if you don't mind the FWD format
In terms of value for money and depreciation, i think (subjectively) that the DC5 will hold its value better as it is newer and also P-Plate legal - thats where the money is atm, in naturally aspirated cars - i think so anyway
All the best happy hunting
Pictures also don't hurt =)
