If you talk about the time it takes traditional banks or local banks now to send funds between banks or between accounts, I think it is still faster because it only takes me a few seconds to send money via mobile transfer or ATM.
Bitcoin may be quite slow with a delivery time of 10 minutes, because it uses the regular Bitcoin Network, if it uses the Bitcoin Lightning network it will be faster and cost less.
Bitcoin does have a few more advantages regarding privacy issues and lower costs if using the lightning network. there is no intermediary and it is fully controlled by us as asset owners.
