Zerodha, Upstox, Groww,5 Paisa...-Which one is good?

Hello Grapeviners, Which one of them is overall good to have demat account for share investments? Asking for my younger cousin brother who is new to all these things.

Please share your experiences, your inputs will be much appreciated.Thanks

PS- I have been using zerodha was very much satisfied with the app ,till they change the details page for stock.Earlier it was ticker but now it is Tijori which is much harder to navigate the details as UI is not that good as earlier in Ticker.
