I'm quite fond of the Alex myself, but I haven't played them all as extensively.
Norris his custom suit by far.
It's been so long since I've fought in Midgard.(Freya)
ez8 for his weapons spam. although it has been nerfed a lot from next+
Hildolfr, Dun Goufed, and Zudah. In that order. All the other ones are not nearly as good.
Gouf and Ez8. Haven't run into enough good Hildolfr's for it to warrant any attention.
Gouf Custom, Berga Giros, and Zaku II FZ in order. Next would probably be Zudah or Hildolfr. I wish I could say Qubeley MkII, but I'm pathetic with her.
I've seen some disturbingly effective LaGOWEs as well.
Currently playing: Kidou Senshi Gundam Extreme Vs. (PS3), Phantasy Star IV (Gen)
Those grenades, man.
Gouf Custom seems to be the best, but the Hildolfr is also good. It just takes a bit more skill to use than the Gouf Custom I think. However! Don't underestimate the power of the Zaku II Kai, heh. Once you get EX with that unit, the grenades are damn crazy.
In general, the grenades are really nice as it is. I've pissed off plenty of people by winning with my Zaku II Kai from just hurling grenades all day, lol.
Currently playing: Gundam Extreme VS (PS3), Sengoku Basara 3: Utage (PS3), and Final Fantasy XIII-2 (PS3)
Waiting on: Gundam Unicorn (PS3), One Piece Kaizoku Musou (PS3), and Virtua Fighter 5: Final Showdown (PS3)
LaGOWE for me since it's the only 1k unit I'm decent with.

I'm going to say Bernie's Zaku II. Decent melee, but you don't use it for the melee. You use it for the machinegun spam, its remote detonated grenades, and the fact you can troll melee attackers by dropping a Santa bomb in their face. The assist isn't half bad either, two Hygoggs.
On top of all that, Awakening gives it triple grenades, still remote detonated. Oh, did I mention those grenades reload incredibly fast?
Close second for me would be Hidolfr. No melee that's worth speaking of, but it's probably one of the best ranged supporters in its cost range. Anti-tank round spam, not to mention its unique HE, AP, and flak shells make the thing insanely good at pounding from a distance. Not to mention the duration of its boost dash is just ridiculous. It's about time we got a tank that wasn't a joke.
Third, believe it or not...Acguy. Why? Because it's Acguy. Nah, but seriously, Acguy's assists are incredibly varied and useful. It may not be so great in direct combat, but the sheer variety of roles its assists cover make it a force to be reckoned with. Not to mention its EX attack has a ridiculous duration, and works well with the previously mentioned assists.
Have not used Gouf enough to comment, though his Heat Wire grappling seems like a good secondary movement. The fact it only gets one use of its shield gatling gun kinda hurts it though.
Didn't have much luck using Ez8 when I tried it, but maybe I was just using it wrong.
Didn't really see much point to the NT Alex. When you lose its Armor, you lose half its movelist, and its non armor moveset seems kinda subpar. A single shot beam rifle, extremely limited melee compared to other units in its cost range, like the RX-78-2...Yeah. I can see why JP communities have placed it at the bottom of the tiers.
