should I use bitcoin segwit or native segwit
what is the difference between bitcoin SegWit and native SegWit
Use native segwit , so you have lower fees. Using a legacy address is pointless as it simply means slower confirmations and higher fees. Under the gear icon on top right click experimental features Native segwit to allow bech32 addresses as well which are even better , but you may want to also use a regular p2sh segwit account because some businesses have not upgraded to accept the newest address types.
