The learning curve of FPGAs is steep because it's a completely different way of thinking. And if you're thinking about a particular application, I agree that the Cypress chip might be the best solution in a bunch of cases. But the original question was which would be a good FPGA learning platform. I don't think the Cypress MCU are the best way to learn about FPGAs. Similarly, your example of a system clock is only relevant if you're thinking about designing your own boards. That's even more beyond the scope of the question.
