What is your Favorite unit?

If you had to choose one unit that you consistently get good results out of, and enjoy using - maybe that epitomizes your play-style - what would it be? and why?

For me, it would be..

Unit: Reaper

Reason: Whenever I have to hold off multiple players or have a terrible team and expect to be horribly ganked, I get out Heavy Vehicles and amass Reapers. With decent retreat-repair micro, they allow me to take a horrific beating and keep fighting back long after all sense would say I should be dead. The high alpha of their attack is ideal for suddenly leaping forward with a few and ganking a high priority target, like a pesky penetrator or commander. They are fast enough to get out of trouble and responsive to micro, and they are tough enough to survive and slay most of the 'nooby' units like snipers, penetrators, hammers, morphed commanders etc

It is dependend on the game size.

1v1 or 10v10?
Big or small map?

If there is only a small area to defend, I prefer units which can retreat - dependend on situation.
I have not really a favourite unit now where Athena is unploppable.

But Bandit and Reaper are both nice.
I like rez-bots too, but that is not early game.

The downside of tank fac is that the only riot unit has low health points.

my favourite unit is the commander!!!
You get it for free, it can morph/build, you can enhance it with modules, it is instantly available and has a good weapon + good hp for cost.
It also produces ressources.

If I could, I would only produce support commanders and AA!!!

My favorite unit is the Pyro. It is the best raider, and has a jump. Microing them is fun, and they can easily kill new players in first five minutes. They make cost vs almost all coms, and keep doing damage after they die, along with their explosion. My elo has gone up by 200-300 since I started using these right (and not playing team games).
My two second favorite units are the Jack and the Skuttle. The Jack counters everything except raider spam, heavy porc, or high-cost units (lvl 4 com, DDM, Dante, etc). The Skuttle is ideal for killing annoying unit clusters (especially shield armies), low-mid HP coms, or any economy (fusions and adv fusions).
These units all help me play by countering anything the other player has out in their same role (with a bit of micro or the fight command) at the early-mid game, and I can expand easier with it.

Reaper and Ravager are up there. They are dependable and if you don't know what to do they are safe to spam. I once filled the middle of The Hunters with Reaper, and they quickly killed assaulting Detriments.

But Crabe is cool too. Or Cloaker + Jack, Tick, Roach...

Cudgel
Because it is the cutest looking Kbot in the game, dont you just want to cudd(g)le it =^o.o^=
