Evaluate if makes a difference: Require Bech32 for higher anonymity set?

The main difference is that P2SH-wrapped segwit puts the witness program in the redeemScript, adding 22+ bytes when you spend the input, but native segwit puts the witness program is the scriptPubKey and leaves the whole scriptSig blank.

Native segwit (bech32) is cheaper but still extremely rare:

$ bitcoin-cli getblock $( bitcoin-cli getbestblockhash ) 2 | grep type | sort | uniq -c | sort -n
      1             "type": "witness_v0_keyhash"
      4             "type": "witness_v0_scripthash"
     19             "type": "nulldata"
   1013             "type": "scripthash",
   5202             "type": "pubkeyhash",

You might want to wait for more people using it before adopting it in any situation where you want your transactions to blend into the background noise.
