But I much prefer use mycelium for faster confirmations tho, and electrum for multiple sending.
Faster confirmations? I don't understand how the wallet has anything to do with confirmation time... The confirmation time is based on fee rate and the current network conditions. If you send identical transactions from WalletA and WalletB at the same time, both with fee of X sats/byte, they should theoretically confirm at the same time.
The network has no idea what wallet they've come from, so saying "WalletA gives faster confirmations than WalletB" is nonsensical.
