I've always liked CTS pots, they usually tend to feel very smooth when you rotate the shafts that the control knob attaches to, definitely a good upgrade for most guitars.
OK, so nobody put their hand up to try the 500K pots & I like the 250K Strat set so I have asked for the long shaft set to test & use in a Lester solid body build.
I'll do some testing when they arrive & post my findings in a new thread.
