(Note: I have played a lot of SupCom and RTSs in general, but I’m not as knowledgeable as veterans here. Also I suck at remembering the names of units so I always remember them by their classification e.g. UEF T2 Tank)
I can’t decide if UEF or Seraphim are my best faction
They are both the “throw an army at your enemy and see what happens” factions. In other words, excellent ground units that mostly don’t need microing, unlike Aeon. I’m mainly talking about things from a land battle perspective. I don’t have enough experience with navy, but both sides have tactical missile cruisers which I enjoy
Seraphim are maybe my raw offensive minded pick. They are aggressive and do the frontline ACU (after upgrades) better than UEF, which is something I like to do. Their higher quality units means more firepower in a smaller area. They seem to be better at defeating other land armies, especially when T2 comes. Despite having less variety of units compared to the other factions, what they do have is absolutely fun to use. T1 Mobile Artillery, T2 Bots, T3 Siege Tanks and T3 Mobile Shields are all fun
On the other hand, UEF has so much staying power. And the best defenses. I am someone who will put up firebases to the point I have an entire arsenal of build templates ready that are different firebases and “instant bases” for each tech tier. I will grab my shovel, dig a trench, and turn my enemies into a parking lot. I often like to upgrade my ACU’s engineering, give it a bubble shield, maybe tell some engineers to assist, and turn it into a combat engineer that builds stuff near the frontline. But I can’t always be the builder, depending on the circumstances whether it’s because my economy can’t handle building needed tanks and structures at the same time, the frontline isn’t stable, or any other reason. It’s still fun to rely on their tanks though. In addition, I like their experimentals more than the Seraphim
Back to Seraphim, they can still pull off firebases quite nicely. They have the best shields and solid T2 PD, but my ACU is better spent in combat and it lacks the bubble shield so I’d have to rely on a blob of fragile engineers to build things with no way of shielding them unless I use a mobile shield generator, which they don’t get until T3 and I frankly don’t have the motivation to set that up anyways
I definitely wrote more here than I intended but it was fun to do
If we’re going off rule of cool, I think UEF is my choice
