I don't know if YNAB is worth it for you, what do you want it for? it's not really like Quicken.
We use both Mint and YNAB together. Mint is much more like Quicken, it updates accounts automatically and is free to use, so you may want to try that first. It is great at tracking all accounts, net worth, retirement goals, etc. I have encountered a few bugs, all of which were resolved quickly or are issues with my bank not Mint. The budgeting is on par with Quicken (ie sucks) and there are a lot of sponsor plugs because hey it is free.
YNAB is budgeting software, and it does it really well. We use YNAB to track checking, savings, and credit card accounts (4 accounts total). Updates are not automatic, but I download and import transactions from the bank very easily, and the only transactions I tend to enter by hand are checks or complicated receipts where I need to split categories before throwing the receipt out. The program will match transactions if you enter manually, so no double entries if you also import. And I can't think of any bugs I've encountered other than issues with dropbox to sync with the mobile app. But we do not use it to track investment accounts, retirement planning, or loans.
f you go with YNAB, there is a trial period, and you can ask around for a referral code discount.
