Not very different, nor was there any real chance for them, as the native Americans were using weapons of Stone, bone and wood vs Steel and Iron.
Spain would simply have sent more forces, it had plenty after the reconquista.
I recently read - and highly recommend - Bernal Diaz's account of the Mexican campaign, called "The Conquest of New Spain." Diaz was a soldier on the expedition, and he wrote "The Conquest" a few decades after the campaign as a rebuttal to second-hand accounts that he says got the facts wrong. The book is considered to be one of the best and most honest of its kind by many historians.
As Diaz's account makes clear through battle after battle, the Aztec ability to muster numbers and their willingness to take heavy casualties made these technology advantages irrelevant. The real advantages the Spaniards had were horses, boldness and skilful diplomacy. Cortez would be a dead man before he'd ever seen Tenochtitlan if it wasn't for his ability to build alliances and turn the natives against each other.
I encourage everyone to read that amazing account. Since historians now tell the tale in a paragraph or two as though it was inevitable, Diaz's story actually has a suspenseful feel to it as well. Until I went to Mexico and grew interested in its pre-contact and contact history, I always assumed it was simply a tale that went like this: "using superior technology, Cortez scared the Aztecs into submission to his God-like form." Not that simple at all!
Once you do read more closely, I think you'll give those Spaniards more credit: they were gutsy bastards, accomplishing far more than could reasonably be expected under difficult circumstances.
Yes, America would have fallen eventually, but without Cortez's skill, Pizarro's shameless boldness and a lot of luck, it would have taken much longer.
