For the most part, I find Evan Williams to be undrinkable. I haven't had their Bottled in Bond but their black label is terrible.
I did enjoy their single barrel, though. So that stands out from their offerings.
As far as drinking it mixed with ginger ale (or beer), pretty much any bourbon is drinkable that way IMO. I've had plenty of Beam and gingers, and I would not want Beam neat or over ice.
