But I can't find an alternative that has cracked the killer feature: Syncing with each of my online accounts. I like to track every expense and every transfer down to the penny, and then update from the bank's online connection to confirm each of them. I do this daily so I can catch any fraud or mistakes. I have 27 accounts tracked, and I'm simply not going to log in to each of them using their janky web sites, download CSVs, and import them manually into personal finance software. It's just not going to happen. Quicken's support for this is far and away the best out there.
Doing this all in plaintext and copy/pasting from downloaded CSVs every day seems like an absolute nightmare.
Unfortunately, the trend seems to be banks turning down their public-facing OFX services, and instead moving to the model where Intuit is the middleman and you need to tether yourself to them, who in turn channel your requests to the banks. So it's been getting even more and more difficult to escape from Quicken.
