MPA3 hands down - beyond the fact that Mansion is a top notch tech company (with multiple XBIZ Awards to its credit), the product works -- awesomely.
More importantly, when evaluating these systems, take the tour, run the demo, examine the supporting documentation. There's many fine scripts on the market that do wonderful things, from automating CMS (like Mansion's kick ass MAS) to running TGPs -- scripts are everywhere -- but most are woefully undocumented, leaving many users with very steep learning curves, to the point that many of the best features are never utilized or maximized.
Mansion's docs don't leave you guessing. And if you still have questions, their support is first-rate. Those reasons alone make its products a wise choice. Add the value of its industry-leading feature set and reasonable terms and MPA3 becomes a no-brainer.
