I have a low end Grizzly table saw which has a arbor speed of 4700. I
switched the motor and arbor pulleys so that the smaller one is now on the
motor. The saw now seems to cut much smoother and has more power. I don't
know what the arbor speed is now with the pulleys switched. Is there any
reason I should not keep the lower speed arrangement?

Ultimately you gained more power. If you are happy with it you are fine.
