they both at their core do pretty much the same thing, jamba has more features like the targeting macros and better quest handling (abandon quest/choices) plus the push to slaves functionality is a nice feature, the buy feature is nice. Don't get me wrong, I really like jamba, I've used it. Multiboxer is just a less complex/featured alternative that does only what I need without the bells and whistles.

Multiboxer feature list is on our very own wiki: http://www.dual-boxing.com/wiki/inde...n:MultiboxerV2
and the thread: [Addon] Multiboxer V2

it was state of the art for quite awhile
