Kotak Standard FlexiCap vs Parag Parikh Flexi Cap


I have been investing in Kotak standard Flexi (formerly kotak standard multi cap --> kotak select focus) for the past 3 years.
The returns for Q1 FY 2021 is ok but the returns for the last couple of years have been average.
Parag Parikh flexi cap on the other hand has been performing very good over the years.
It is well diversified and it also invests in top US tech stocks, it has been beating the benchmark consistently over the years.
Please advise if i should switch to Parag parikh flexi cap from Kotak flexi cap Or is it advisable to invest in both as the fund overlap is around 15-18%
