Ottomans! Hands down.
Bring in the mighty Janissary and all is lost for the Spaniards.
Add that to the command of Suleiman the Magnificent and ...
well... Resistance is futile

Fabius Maximus

I think it was around this time that Europe started to pull away from the Islamic world in military terms, so my money would be on the Spanish. I think, however, that the actual war would be pretty indecisive: neither power would be able to take the conflict to their enemy's heartland, so total victory would be impossible, even if one or both sides wanted it. Probably a few Ottoman possessions along the coast of Africa would fall into Spanish hands, and there might be some sort of indemnity, but apart from that I can't see much changing.

I think the war would be indecisive.

I think Turks would never lose against Spanish on European borders in case of a battle in open field.Spanish may occupy some far North African territories of Ottomans.

The Ottoman empire at that time was a lot wealthier then the Spanish Habsburgs, Charles V could only dream of the financial assets and forms of taxation that Süleyman enjoyed while the former had to subdue his own cities because they revolted over ill run negotiations over taxation. As far the statistics would go, the Spanish Habsburgs had little on the Ottomans.

Tercio

Well the thread specifically says up until 1550. Before the economic inflationary probelms of the three phillips. Also you're point about the military is complete rubbish. Spain had the most professioanl army in Europe at that time. Do you remember the famous statement from Suleiman the great stating "for every Spanish infantry we face we must muster 3" or along those lines? Also this was the time when the Europeans were technologically pulling away from the Ottomans.

Evidence of Spanish battles singlehandedly won? Siege of Castelnuovo, look it up, 3000 Spanish tercios inflict 20,000 ottoman casualties and destroy a large number of ships. What about the sackof Tunis? (Yes I am aware of what later happened, but nonetheless it is a victory). Or perhaps the battle of Sisak from the army of Flanders?

Yes, except for superior diplomacy and infantry. I think that the fact the Ottomans could not beat Austria even when they went all out proves that they won't beat Spain. Also Tercios>Janissaries. But the true key, is that if they went all out we would witness most of Christendom joining Spain, the ottomans would get france if they were lucky depending on the date

Tercio

Btw look at who actually won the war. Whilst it weakened both, Spain came out on top because of her European Allies

I guess if they didn't win against Austria, they wouldn't win against Spain either. Probably Spain after the conquest of the New World was more powerful than the Ottomans

The Spanish gained their powerful reputation from conquering who? The Native Americans?

The Ottomans gained their powerful reputation from all the conquests they achieved in Europe, Middle East, and North Africa. Places where nations are actually just as civilised and perhaps even more civilised than the Turks.
