In a spherical-cow sense bitcoin is better. In practice, if I'm paying with amex I tap my card on the reader and the waitress hands me the cup of coffee in seconds; if I'm paying with bitcoin I'm standing there for half an hour.

If a friend's sending me money it's by "faster payment"; theoretically it can take up to 2 hours (similar to bitcoin's max times), in practice it's a couple of minutes. My bank's happy for me to "spend it instantly" in terms of not charging me an overdraft fee (in fact I can spend it before I get it, as long as I put the money in by the end of the day), so I have GBP1500 (let's call it $2500) of float.
There are edge cases where this doesn't work - more than $2500, or paying internationally over the internet. But they really are edge cases; the problems bitcoin solves are problems I've never had, and I suspect that's true for the vast majority of "normal people".
This is a myth. Once the transaction has propagated through the network, it's pretty difficult to double-spend, even with zero confirmations. So difficult, in fact, that payment processors like Stripe/Coinbase/BitPay will completely absorb that risk for you and consider the order complete within a second or two of seeing the transaction on the network.
Try buying something online with Bitcoin sometime, it really is faster and easier than using a credit card (if you already own some).
Current block size limits bitcoin to ~3 transactions per second. It would take bitcoin 22 days to handle just 1 day of Visa's global transactions.
This is a serious problem because in order to increase the block size, it requires a consensus amongst all miners, merchants, etc.
Bitcoin effectively suffers from Tragedy of the Commons, because it can't scale unless every rational actor stops trying to get their own profit out of it.

This really is the fundamental difference of bitcoin- once the money has moved, it's really moved. It takes some time and thinking to appreciate how that opens things up quite a bit.
