I have both and go back and forth between the two. However if you are going 10 days I would want something larger than my Exo 5500 and I would use my Sky 7200. If Exo made a larger bag, then you might have more of a debate.
These packs were packed for a 7 day trip. One is a Sky 7200, the other an Exo 5500.
A few different pics here. You can see how stuffed the Exo was. It got smaller as I ate up the Mt House meals, but definitely would like to see an EXO 7000+
I think both packs are solid packs, the gripes I have with SG were around how the shoulder pads fit, that has been addressed with the newer frame.
Exo fit me better out of the box, buy SG worked hard to dial my fit in and nailed it.
For 10 days + I'd lean toward SG's current version of the Sky 7200 (Sky Guide)
For what it is worth, I pack light, but am not an extreme light weight guy.
Good news is both companies have great customer service, quality products, and support Rokslide so you really can't go wrong. : )
