I have the 5760 (one step above the 5750) and I love it- one of the main differences is the 5760 has the YPAO (includes mic for auto set-up). You might be able to find the 5760 for just a bit more (if you can squeeze out the extra cash). However, if you go with the 5750, you should still be satisfied. Both Pioneer and Yamaha make good quality receivers so I'm sure you'll be pleased with either. If I had to make the choice, I would go with the Yamaha- mostly because I'm already familiar with their products.
