If you have the cash to lay out for a Scoob or EVO for every day car then do, they may be more driveable but on the other hand if you grew up in a Ford heritage orientated family then owning a Cosworth is simply the natural way to go. I grew up with only Fords in the family and now that I am older I own a Toyota for my daily driver, BUT that did not stop me from buying a MK2 just to tinker with and there is also my MK1 in the garage waiting for the Cosworth heart to be transplanted..
People have way different views but I still go along the lines of heritage, it's a RS thing
