Ketan - from a systems perspective, the real benefit of Quickbooks is it has the architecture to allow multiple users and assign different privileges to different users. If you will be the only one entering [journal-ing] data, Quicken should do the job.
One thing that I have learned from clients over the years is that you should check with your accountant to see what they will work with. I know some accountants insist on Quickbooks, and they will setup your chart of accounts based on several factors, with the mindset that your data will be pre-aligned for your business structure, and therefore much easier for them prepare various submissions. [and in theory cost you less to prepare]
