Actually I think I've liked all factions I've played so far about equally. But since both Romani, Arverni and Kart Hadastim got blocker CTDs (I played them in earlier EB versions) I never got to finishing them and never got to try out their better units. So far Baktria and Makedonia are my only smoothly working campaigns. But Baktria was completed before I got to try out their later units, so therefore I don't think I can evaluate any other faction than Makedonia completely. I've now got to a stage where I can have a solid line of 6-10 Pezhetairoi, 1-2 generals, around 4 Hetairoi, a few Leuce Epos or Curepos (mercenaries or recruited in for example Tylis), 2Sotaroas/Sphendonetai/Toxotai/Akontistai/Peltastai, and 1-4 mercenary horse archers recruited in conquered Getai territories... A lot of flexibility. Baktria was interesting, exotic, and gave me a chance to face both phalanx based armies (arche seleukeia), and horse archer based armies (Pahlav, Yuezhi). It's a difficult choice but I think Makedonia has been a little more fun, due to the fact that finally most CTDs are gone and I can play many turns in a session so the AI too can expand. Makedonia also has a more interesting position where they have a potential to at some point in a campaign go to war with 90% of the factions, unlike Baktria which is at a map edge, so it makes for an interesting diplomatic situation, where my aim has been to avoid war with too many at the time, with the result that I've been able to keep up trade and income while I was fighting my wars On the other hand Makedonia has almost too good income, I've not had any economical problems at all since the beginning of the campaign, and short supply routes from training facilities to the front, but the latter might be because I'm finally adapting my playing style to the supply situation, choosing to whenever possible only expand where I can reinforce my troops easily.

Favorite unit is equally difficult to choose but I like leuce epos and curepos, as they've inspired me to new tactics and opened my eyes to the usefulness of javelin-armed cavalry. For a solid line, Pezhetairoi, Principes (and my mercenary Samnites) are very fun IMO. I also remeber liking the Pantodapoi phalangitai a lot in the early stages of my Baktria campaign. The Gaesatae are very fun to meet, and gives a sense of accomplishment when you can defeat them (but I've not yet used them in my own armies). It was very fun when my Makedonian troops got to fight a rebel army with 8 of them in Ankyra and managed to defeat them So they're probably my favorite enemy unit at least. Favorite unit to command is more difficult to choose.
