I'm 5'6" and i find that the swift's legroom is fine. I was at a dealership this monday and with my father (same height as me) sitting on the driver's seat adjusted to his preference, i still had a lot of legroom behind him. I daresay if not on par, just slightly less than our altis so i don't really think it is too tight. The celerio is worse so you will be better off with the swift space-wise. If it is worth the price premium, that's for you to decide.
