As has been mentioned, it's always a good idea to measure the values of the pots that you're using. If your pots have a 20% tolerance, that means that a 500k pot could be anywhere from 400 to 600k . . . and that's definitely a big enough difference to hear.
I've got three of the Bourns 500k cermet "Premium" pots here. Two read right about at 400k, and one reads 384k. This is with a good quality, calibrated Fluke meter. The 384 isn't even in the 20% tolerance.
I generally swap out pots only if there is static I can't get rid of with DeOxit, if I don't like the taper, or it doesn't turn easily enough. As far as that last point, I like my volume and tone to be super quick and friction-free. I do a lot of volume and tone swells.
You do know that 20% tolerance means ±20% right?
You can just measure the pot to verify.
