i value the looks, FC, value for money...practicality, that is...so Tucson CRDi premium has my vote!
Forester obviously has more horses than tucson but hey, are you really going to use those extra horses of the Forester against Tucson's that often? if you do, and paying more for the gas doesn't mean anything to you sir (not to mention being green nowadays, hehe), then by all means, Forester xt it is!

lastly, IMO Tucson looks proportionally stunning than the Forester which is boxy and bad profile...
