If anything, Huxley and PlanetSide are equals, depending on the player.
Huxley promises large character development and customization, while also having PvE combat and a loot system.
PlanetSide on the other hand needed more strategy, but was more repetitive than it needed to be. (All the buildings were pretty much the same D
So yes, the games are both different AND each have their own strong points, I believe that which game is better varies from person to person.
I myself have UT'04 and the Invasion mod which adds leveling and PvE against monsters and dungeon bosses. Just the ticket to practice for Huxley.
I have also played Vanu Sovereignty, riding around on Conglomerate territory in a cloak suit capturing towers that are major spawn points for them - BEFORE any wars broke out, then my guys would swoop in and make easy pickings because all the good spots were taken. Blah blah blah (Giving myself too much credit) Blah blah.
I type too much.
