We are currently using Memberclick AMS (Oasis) and LMS. This is our first AMS that we have ever used, so I don't have anything to compare it to. The customer service is great at Memberclicks. Our concerns are addressed, fixed, in a quick and professional manner. Having said that, the Memberclick team knows my employee by first name. We have had a lot of issues reguarding integrating the AMS with the LMS.
