I ended up getting the Analog Cases bag on sale, but I'm debating returning it. The Gator bag looks superior: Better accessory compartments, internal straps to secure the Pro 3, has a shoulder strap, has a sternum strap on the backpack straps, has additional protective plastic on the corners and bottoms. A standard Pro 3 in the Analog Cases bag has too much room. I have the Decksaver and it doesn't stay on very well in the Analog Case due to lack of strapping and too much space. So I either need to strap it down around the Pro 3 or send the bag back and get the Gator bag.
Anyone considering the two should definitely go with the Gator bag for the standard Pro 3. For the Pro 3 special edition you might need the Analog Cases bag unless you go with a flight case (heavy!)
