Gear also is a good factor, but I guess that also will be based on your rank? Also packs available are pretty wide ranged, but NX users have a huge advantage in net speed.

Advanced / Utility are the GP packs for 2/3 slots respectively, while NX users have the Terrain Backpack. 2 / 3 slot version of that offer a 2% speed bonus, giving you a slight advantage but it's at a high NX cost. At least in respects to the original NX packs. :P
