The only people here saying Footlocker is better are 25+ yr olds. Any kid that says they want to go to Footlocker over NXN has been influenced by a coach or parent or local runner who regales them with tales of how amazing Footlocker is/was (and it truly used to be great).
The only thing Footlocker has going for it is that it is in San Diego. But even though Footlocker puts the kids up in the glamorous hotel del, that's got nothing on Nike renting out an entire hotel and filling it to the rim with high schoolers.
Footlocker is somewhere between Myspace and Facebook. NXN is Twitter/Instagram/Vine.
Footlocker is VHS, NXN is Bluray.
Footlocker is Red Lobster, NXN is well, anything is better than Red Lobster.
The Footlocker gear is 2nd rate, their guest athletes are 2nd rate, the field of athletes is beaching 2nd rate as well.
