The ability to have one place for all your financial data, this also makes it easy if you need help with any issues related money in general! It's not too user friendly at times but once I figured out how everything worked its been great so far!! Nothing really bad about using compucal - just make sure when signing up they offer an option where there are no hidden fees like some other companies do because otherwise i would say avoid them completely unless their price point fits within what yuo want/need from such service provider!
