It is worth mentioning that Ethereum had a rollback of a transaction back in 2016 (I forgot the exact year) when there was a hack. They had a hard fork to get all the assets back for a DAO. Ethereum Classic is the real Ethereum as some of the folks didn't support the hard fork.
How much weird this sounds lol! People should be more aware of what's a secure transaction. It's definitely not only about getting transactions faster, satoshi could do it faster too. Though the reason behind is not the same, there's a reason of course why it's 10 minutes.
I'm not much interested in Ethereum for various reasons. I stick to Bitcoin mainly because it embodies a few very unique design principles that Ethereum lack (no shady premine, decentralization, trustless, deflationary and limited to name a few important ones).
But Bitcoin had a small rollback too in the very old days, when due to a bug someone "produced" something like 184 billion Bitcoins out of thin air. Quick find (likely not the original thread):
How someones made 184 Billion Bitcoin appear out of nowhereP.S.
