Pick-Up and Mileage will be approximately same for both cars since they share the engine. Ritz is more comfortable of the two owing to softer suspension setup and that it has more head room at the back. Handling-wise and resale values wise Swift is ahead of Ritz. As far as looks are concerned, beauty lies in the eyes of beholder so whichever you think is beautiful is beautiful for you.

My personal pick would be Ritz.
