The best approach is to consider the features that you will use the most and compare their implementation in either package. Compatibility with other programs was once a bigger issue than today. Law firms standardized on WordPerfect because everyone else was using WordPerfect. This made exchanging documents with other law offices, clients, and courts easy. However, the Windows environment has eliminated this barrier and you can freely exchange documents with Word or WordPerfect users.
Document conversion is handled automatically for an extensive list of programs and versions.
Also, you can save documents in any format you choose. Another factor that users should consider is the platform they prefer. This involves two independent issues. Application integration is an important consideration and can greatly enhance productivity. Some users may prefer Microsoft and their applications because they see this as a stable company with few surprises in the near future.
