Holy Smokes - talk about no parameters to fence me in ! Yeehaa!

I'd have start with it depends on the application:

Tactical:
Never owned an AI but guys love 'em
GA Precision makes nice rigs that always shoot well
My preference is Mark Chanlynn at BigHorn Arms using his custom action (tell him what you application is and what bullet you want to shoot and he'll match you up with what would work well.)
