As stated by Prime
In terms of replay value, JA is probably much longer than JO. Just the light and dark side choices alone at to this substantially...
Exactly. When I had finished JO(admittedly needing to glance at a walkthrough a few times) I just went 'phew!' and went back to playing something else, not returning to it for a while
In JA, I am having a great time re-doing levels, trying the customisations, trying to get the saarlac to eat the spawned mutant rancor etc......
that blenjeel level is much more fun when you spawn a rancor or two, and a swoop - and then dash around looking for those parts !!!
