I think it's kind of implied that the Legion have superior numbers, and that's why they're so terrifying. And they're not as poorly-armed as people seem to think either. I like to think they fight sort of like the empire that inspired them. Lightly-armoured and armed Hastati in the front line, these are your recruit legionaries with machetes. They'll break a Tribal force without much problem. Against the NCR, they will possibly cause some casualties, but mainly they will force the NCR to reveal their positions. After them come the Principes. Veterans. More heavily armed and more experienced. They're the ones who will have Cowboy Repeaters and the like. After that the Triarii, the elite, battle hardened troops, held as a reserve.
In open battle, this would work quite well. Against an entrenched enemy, it would pretty much be suicide. The tech level of the Wasteland is about WW1, trench warfare levels. Defensive weaponry like machine guns are well-developed, without anything like heavy armour, widespread artillery or aircraft to destroy them. The only thing stopping any conflict from turning into a trench war slogfest is a lack of numbers. If either side is defeated, and are being smart, they will simply retreat to a choke point and fortify it. It would be very hard to utterly rout a well-prepared enemy when they have that option available to them.
As for who I'd prefer to live under, the NCR or independent New Vegas. The NCR has problems, but they are fixable from within. The Legion is brutal, reactionary, and is likely to descend into civil war when Caesar dies. Compared with that, a bit of corruption in the NCR is small fry.
