Best and consistent mutual funds to do SIP

Hi GViners, I need your help in selecting MFs I am looking for best and consistent mutual funds where I can invest. Primary Criteria is it should have given best return consistently with low expense ratio.

I was doing SIP of 10k-20k/month when I was previously working but looking to increase my SIP amount to 50k/month as I switch company.

My previous funds are as below(all were direct growth fund): ICICI Prudential Bluechip Nippon Large Cap Motilal Oswal Mid Cap Quant Midcap Quant Smallcap Nippon Small Cap Aditya Birla PSU

Should I continue with them or add any new funds as atm my portfolio is not big so can change.
