Which site should I use for a mutual investment, Upwardly or FundsIndia?

Two main things to help you which one to use. Go for a site that offers only Direct Plan Mutual Funds coupled with strong advisory capabilities.

1. Needless to say, Direct Plans help you earn more and website that earns indirect commission from your investment can be skipped
2. You can judge advisory capabilities based on the quality of the advisory team, depth of the content they have written, and also by speaking to some of their customers.

Having said, that do take a look at Jama.co.in that offers the best of both these criteria.
