well the scion has a bigger engine and will use more gas and also weighs more but not by much though....and the civic is about $2000 more than the scion ....i test drove the scion before and it seems quite slow to me....in all aspects if i was u i would just test drive both vehicles and see which 1 u like the most it might take a few trips to the dealer ship and test drive multiple times but i would think u will like the civic more than the scion TC and also the honda civic has been out alot longer even though toyota makes scion i would think the civic will last longer and easier to maintain.....i also attached a web site for u to compare the vehicles....but i would test drive the vehicles that way u know what u are getting urself into before buying it....if u plan to do mods to the vehicle the civic will be easier to upgrade than the scion as well
