What do you mean "better"? I think it's hard to say what "better" if we are talking about types of transaction (in fact, just insctruction how to spend outputs). I don't think that Segwit P2WSH is better than P2PKH.
With 'better' i was refering to the total amount of fees OP has to pay while using the same amount of UTXO's as input (compared to P2PKH).
Additionally segwit (bech32 and nested P2SH) are capable of being supported by the lightning network. Segwit is a requirement for a second layer solution at the current state.
So IMO it is 'better'. Nore sure about the cons regarding segwit. Feel free to explain.
