1. ClientExec doesn't have instant account setups for cPanel nor any other control panel, you have to manually insert the members.

2. WHM AP has all the features (even the trouble ticket system) that ClientExec has PLUS you can be worry free and you can get the account setup instantly and easily without any hassle of logging into the root and adding the account, filling out all the information, really becomes a pain when you're getting around over 25 members daily or more. <_<
