Recommend a Third-Person Controller Package

Hi there... I'm building a 3d Scifi RPG. I am not an experienced Unity programmer, so I'm planning to use a thirty-party character controller package. I've tried several packages so far, but I wanted to see if there are specific suggestions in case I've missed the best options.

I need to have the standard RPG movement capabilities and actions, as well as shootable weapons and melee combat.
I'd like to have a solution that is easy to adapt to microgravity movement and combat.
I don't want a health/combat system... I've got my own I'm going to use.
I don't want a UI system that I can't easily remove to use my own.
I don't need a built-in AI system (I'm looking at Behavior Designer at the moment).
I need to have documentation (video and written) that's clear, complete, and doesn't assume I'm a master coder.

If you've had experience with one or all of these systems, I'd love to know more about your experience and your recommendations. Thanks!

 

Opsive UFPS 3RD Person Ultimatev2.0 I also use EmeraldAI, far better than Behavior Designer.
