Non-spreadsheet budget software cannot offer this kind of flexibility, as the relationships between numbers and the manner of presenting them are limited to the circumstances envisaged by the software designer. On the flip side, quality non-spreadsheet budget software will often be easier too use within the purposes of its design. Also, non-spreadsheet budget software often contains in-built features that the average spreadsheet user would not be able to build into a spreadsheet.
Personally, though I have tried out some of the different non-spreadsheet budget software, I always come back to spreadsheets. Its the flexibility and perhaps a love of tinkering. The most well-known spreadsheet software is of course Mircrosoft Excel, but these days there is also lots of free and open-source software available such as OpenOffice. I prefer MS Excel. In my experience it is the most polished and functional spreadsheet out there.
