Well, it depends on who you talk to, I think. That was certainly President Richardson's intention, but I'm not so sure about Eden. He was genocidal toward FEV-infected beings, sure, but outside of that I got the feeling that he was more interested in a society built on pre-war ideals than those of the shadow government that inadvertently created him. Maybe it's just me.
Well, as posted before, the Enclave is trying to rebuild America for the wrong reasons and how they wanted to wipe out everyone who wasn't born in a vault or in the Enclave, it reminds me alot of Nazi Germany and Hitler, obviously. But I think the Enclave is on the right track, they have more wealth, and more knowledge and more power than the NCR.
One small factor, that really stands out to me is, basic footsoldiers of the Enclave (F3) were fitted with the best of the best power armour, the best type of protection the NCR has, armour-wise is salvaged power armour from the BoS, which, shouldn't even be called power armour as it can be worn like normal clothes, and is not a machine, because it does not require the special training to wear.
Also, the NCR Rangers, as nail-hungry and fiery-breathed as they seem, have
nothing on a standard Tesla equipped Enclave Power Soldier. The Rangers most likely have a better survivability and a bit more skill but, a trench coat and pre-war antiriot armour and a basic revolver, or maybe an old west rifle, vs. high tech power armour and energy weapons?
The Enclave is definitely the most powerful and capable force, fighting for the Wasteland, that or the BoS. It's a close call.
