realistically the NT was the "golden age of the jedi" which implies they'd probably have the highest population of jedi as they hadnt had war for close to a thousand years, and supposedly they had around ten thousand (or so it was said earlier in this thread) now consider that the jedi order is a couple thousand years old ( I believe around fifteen, though at the moment i seem to have misplaced my source, it's been a long time) so at best we're looking at a hundred fifty thousand jedi (ten thousand jedi for every thousand years) now factor in the fact the jedi order was close to extinction many many times and the overall jedi population is even lower.
However, NJO jedi were much fewer in number and with the exception of Luke quite inferior to their older counterparts and they were more or less able to exterminate the Vong near the end of the war, once they had proper knowledge of their enemy. Factor in the superior numbers and ability of the old republic jedi and they would stand a decent chance in a land engagement agaisnt the vong invasion force from NJO (I am NOT saying they can win, merely that they'll take a lot of vong down with them) However if we're saying all the Jedi that also means all the vong which number in the trillions and therefore outnumber the jedi ridiculously, more so then genosis,and that was only droids, even factoring in the few stand out jedi the sheer numbers are too overwhelming. Now throw in sith and it might be a little more fair...
