In the case of dedicated plate carriers, the TAG Banshee is my all-around first choice. If you are not running side plates or side soft armor, the Beez is less expensive.
Again, to re-list the choices in terms of features and price, they are:
$$$ SKD PIG- Top of the heap in features, and priced accordingly.
$$ TAG Banshee- Excellent balance of features and price.
$ Beez Slick- Best value, durability, and comfort, especially if not running side plates/soft armor. Upgradeable to cummerbund if required.
Hope this is helpful. There are many, MANY choices as far as plate carriers out there, these have been the ones I have kept coming back to.
