IMHO this is the easiest, most intuitive program of this type. I've tried Moneydance (too ugly), Budget (too confusing), Checkbook (too limited), etc. While iBank might not be the most powerful, it's pleasant and great for what I need it for: simple, personal checking, savings and investments. But the only things missing are CSV and 401k support. And a lot of finance/bank websites don't offer QIF, or QFX files.
