It all comes down to fit mate-only trying them on will let you know for sure.
Others are Osprey, Gregory, Pod-sacs, Gossamer gear Gorilla, ULA. The latters would be my pick.
Yes ... but ... I also find packing them with your own kit is important too. Just tried one, bought and took home, but it wouldn't carry as much as my Murmur and was much harder to pack. The comfortable hip and adjustable chest straps didn't compensate so took it back. I'll have a look at all the makes you guys mentioned and see if the local shops sell them - we have Trekitt, Millets and Yoemans in Hereford!
