Investing on Chip App SS: which one to go with?

Hi all

I have some SS investment on Chip but realised im investing in a sp500 tech and in another 'adventurous fund' which is actively managed by Blackrock but basically has same holdings as sp500 tech.

Is it good idea to maintain both or is it better to go with 1 of 2 and if im choosing 1 only then what option is better ?

Looking for thoughts and opinions.

Cheers
