I have owned just about every brand of assault pack over the past fews years. SOE, Eagle, Spec Ops Brand, Camelbak, LBT, DBT/BattleLab, CoyoteTac, Kifaru, et al.
Operationally, I have used Kifaru, USGI, Diamondback Tactical, Coyote Tactical, and LBT bags in Afghanistan.
The Eagle FSBE II Patrol pack (if that's the eagle bag you're talking about) is nice, but too expensive for what you intend it to do.
The RAID is nice, but I found the Kifaru Marauder to be a much better panel-loading bag. Loaded with external pouches, the RAID makes a well-organized stay-put bag. The Marauder does everything the RAID does, but can actually be worn on the move comfortably with up to 50 pounds. I don't know about the newer RAIDs, but the Eagle one I had had no internal PALS. It's one thing I love about the Marauder.
I've never used a TAS, er, PPM bag.
Believe it or not, the MOLLE II Assault Pack (Universal Pattern) is one of my favorite bags. It's well compartmented, has a plate pocket, and is just the right size for overnight outings. I keep mine packed as a Grab-and-Go bag for 1-2 days trips in case someone else flies into a mountain.
Since you're going in public with it, I suggest something a little more low-vis than the bags you listed. Black is best, and I promise no one will make fun of you if you bring it to the field. :lol:
Rather than run on with what I know about bags, how about you answer some specific questions, and I'll answer them the best I can.
-What are you going to carry in it? (Most Important)
-Do you need a frame or framesheet?
-Will you be attaching pouches to the outside?
-Do you need a waistbelt?
I know there are alot of cool bags out there, but I didn't really find packs that suited my needs until I put what looks cool out of my mind and concentrated on my specific needs.
That's the main reason I have 7 packs with me over here! I need a bag to keep my Aircraft Recovery tools in, and sometimes I need to hump all my shit in it for 7 miles. Different packs for different jobs.
You have to realize that there are military bags designed to carry commo equipment, M18 smokes, and a camelbak, then there are bags meant to haul laptops and books. It sounds like you need the latter.
