Programs integrate with each other and the Internet.
Office suites cost less than the sum of their parts.
Check reviews in computer magazines and on the Internet to narrow your choices. Choose the suite you use at work if it is commercially available and you want compatibility, or you want to save the time required to learn slightly different programs. Consider that most businesses use Microsoft Office. Buy Office if you want to have current proficiency in the software your next employer is likely to use. Compare Corel WordPerfect Suite and Lotus SmartSuite with various editions of Microsoft Office.
