8825 vs 4988 drivers

I was thinking of upgrading the stepper drivers on my 10" i3v to the 8825. Is it a worthwhile investment?

If the A4988 is working, there probably isn't a need to upgrade.

If you do, keep in mind that the microstep settings are different (1/32 vs 1/16).

Thanks. I'll put that money towards something else then.
