Balance aside, the lore clearly states that the Chinese had invisible armor, and that American stealth boys are based off that technology. The New Vegas version is a prototype, and therefore it does not need the stealth field, but the one in OA is an actual relic from the invasion of Anchorage, and therefore needs the field. The armor was overpowered, but that does not excuse throwing lore and logic out the window, as obsidian did. The right thing for them to do would have been to change how stealth fields work, so they are not exploitable, rather than retconing their own lore.

Chinese Stealth Armor New Vegas
Until they release a Chinese Steal Suit or equivalent (either perk or armor) I'd say no (but keep in mind I don't own the game). I didn't find Stealth to be all that easy to pull off in FO3 without that DLC Suit just because you'd still get seen and for obvious reasons you don't get enough Stealth Boys to really cover an entire playthrough. The chinese stealth armor works like it's cousin in the OA DLC for fallout 3, 15 sneak and 5 stealth WHILE crouching. There is only one suit of armor in the chest it's base condition was increased from 60 to 100%.
