Aesthetics were a nice side effect of not using it but I shunned the power armor for the basis that it's bloody heavy. Between the PA, my jet pack.
Turns out I didn't really need it anyways due to how sneaking and sniping broke Fallout 3's difficulty curve. Or, should I say shattered? CSA + Silenced assault rifle + 100 sneak + 100 SM Guns = final mission of Broken Steel is a joke difficulty wise.
I wouldn't know, the T-45d and T-51b both look very noble and heroic, which has always been its purpose since the beginning. Granted there is a good logical reason a giant tin can full of motors,circuits, and reinforced steel is 45-50 pounds, its not something a person who prefers scavving/collecting over combat really wants strategically. Me, I always stick to the Combat Armor and the Bandana.
As to BS, I really wouldnt know, My combat skill was small guns, but I focused on my more passive skills to be honest. :laugh:
