One thing I considered when purchasing a PPC software management tool is my budget. A lot of these platforms are expensive so I really had to make sure they fit my budget. Some solutions out there charge by revenue share while others have a fixed monthly fee. Also, many of them have long term contracts which you will need to take into account since if you decide to break your contract, you will be paying some penalties. I haven't used the ones you mention but tried other ones myself for my online business and also I use other ones for my agency where we manage PPC campaigns for clients.

Hope this helps.
