Yes, of course: If you restore a backup, you probably want to do that as fast as possible. Restoring incremental backups is slower because you first have to restore the full backup image and then all incremental backups based on that full backup. (Cumulative backups make this even more interesting.)
So it is a trade-off between backup overhead and restore time: if restore time is of utmost importance, you probably don't want to use incremental backups.
Another issue is if you change lots of things between backups. If the incremental backup contains pretty much the complete database, you can take a full backup as well and potentially turn of the TRACKMOD switch. Again, it depends on your situation...
