Please suggest!

Hello guys, I am investing 50K each in Nippon India Nifty Midcap 150 Index fund and Quant Smallcap fund and later found out that Motilal Oswal Midcap find has better returns. Should I switch to Motilal Midcap fund for Midcap and any other fund for small cap. I am open for any suggestion. I am looking for ~10 years with high risk appetite.
