540 vs 1000 pto pay more for both?

I have to admit my ignorance regarding the pros and cons of either a 540 rpm PTO machine versus a 1000 rpm implement. Everything on my place is currently 540. However, I'm movin' up to a bigger tractor and I'm wondering if it makes sense to pay a little extra and have the option of both pto speeds.

All comments appreciated. Thanks in advance.
