Well I must admit that while the anime (and possibly the manga) didn't give a good representation of Jugo's fighting prowess. That said since the Curse Marks are based off what I can only really call the Kekkei Genkai of Jugo's clan then it seems reasonable to assume that he would be at least 4 times as powerful (with Sasuke possibly being the exception). Plus based on how powerful Kabuto became after incorporating Jugos abilities into himself that is a further testament. Kabuto seems to have implied that with Jugo's abilities he could remain in Sage Mode in perpetuity. Sage Chakra seems to be at least 3 times as powerful as regular chakra. It is possible that Jugo could fight in perpetuity but it also seems likely that he would eventually kill myself doing so (if for no other reason than eventually using a technique he himself could withstand or survive the use of). Plus Sage power seems to be immensely draining to use over an extended period so it seems likely Jugo would eventually die from sheer exhaustion. After all no matter how enhanced chakra becomes by the infusion of Nature energy the chakra network itself has limits (as evidenced by the Eight Inner Gates).
