Old topic I know, but I've recently been looking at one of these two as well. I ended up handling both, but ultimately decided on the 6094A. The reason mainly is that the APC was a little too minimalist for what I was looking for, and I didn't care for the closeness of the shoulder straps. Probably would have gotten used to over time(?), but in the end it was my internal gut feeling that led me to the 6094.
Now, I think deciding between the 6094 and Eagle APC (as pictured on SKD's site) would have been a MUCH harder decision and I quite possibly might have chosen the Eagle. Can't say for sure though.
The main reason I'm posting is that one of my biggest gripes with the 6094 is the kangaroo pouch in the flap as others have pointed out. Thinking about it, I was wondering why LBT wouldn't change this and the thought I came up with is that the LBT kangaroo pouch can accommodate SIX M4 30 round magazines. I doubt the Mayflower can accommodate 6 mags.
That said, I like to keep my front low pro, so I'd only run 3 mags and so the 6 mag capability is not a selling point for me.
Add an internal admin pouch and kangaroo pouch in the carrier front instead of the flap, and the 6094 would be perfect for me.
My thoughts for what they're worth.
