I would say:
1. GFS pickups if you're on a tight budget
2. DiMarzio area J's if you want good hum-cancelling J's at a reasonable price
3. Fralin, Nordstrand, or Duncan Antiquity if you want top notch single-coil J's wound to vintage specs
I think the Fender Noiseless is a good pickup (I've got them in an older American Deluxe with an active circuit) but I wouldn't call them traditional sounding jazz pickups. Even the Fender Custom Shop 60's pickups are overwound which makes a more aggressive sounding pickup.
But here's the real issue for me: if you're willing to spend more than $150 on a set of jazz pickups, then go to a super high quality aftermarket pickup winder like Lindy Fralin, Jason Lollar, or Chris Klein. Carey Nordstrand does great work too although his pickups sound a little more hi-fi to my ears (not a bad thing, just different from traditional vintage sound). All of these guys are super knowledgeable and some will even custom wind you a set based on your preferences (I'm having a P-pickup wound by Chris Klein and he's fantastic. He still hand winds every pickup. He also has 3 different winds of jazz p/u depending on your needs).
At the end of the day all these guys make wonderful sounding pickups. You just have to decide which one makes the most sense to you.
Don't imagine that stock is unacceptable. Listen with your ears, not eyes or wallet. If you REALLY don't like it, replace it, but there's no reason to think that just because it's Squier it will sound bad.
