I bought the Osprey Questa and The North Face Womens Jester at the same time to decide which would suit my needs better. Compared to the Jester, the Questa is nearly double the price, yet I prefer the functionality of the Womens Jester better. By comparison, the Jester is more practical and easier to use in terms of the way its designed; the Questa (in terms of function and useability).
The Questa is 28L and the Jester is 26L but the Jester feels roomier and seems to hold more. In fairness, I prefer the Questas straps; they're more curved and feel more comfortable on my shoulders. Even so, the Jester (filled with the exact same contents as the Questa) carries better on my frame.

I am keeping both backpacks for now, but I know the Jester will be used more often. Ive no regrets buying the Jester, whereas I have some regret buying the Questa. (I also ordered the Osprey Nova, Perigee, and Pulsar. Ill update this review and add reviews for those backpacks when Ive had a chance to try them out.)
