Portfolio review

I have the following SIPs running right now: 1. Quant active fund - 20k 2. Quant small cap - 20k 3. Axis growth opportunities - 20k 4. Nippon small cap - 10k My time horizon is pretty long - 15-20 years. Please suggest what to keep and how much. Please suggest a good alternative to quant active fund and whether i should keep both quant small cap and quant active in my portfolio. For some reason, i have seen quant active give far poorer return as compared to quant small cap. I’m willing to hold, but I’m unsure if i should or shift to nifty next 50 ? Thank you for your time everyone !
