I try not to be too "precious" about knobs... I must confess a secret fetish for the venerable "chicken head" even though I don't have any on my guitars. I do have them on some of my other gear though much to my delight. I draw the line at wrapping 20 or 30 layers of tape around the pot shaft (which I have seen more than once) but pretty much anything else is fair game. If it actually looks cool, well, that is a bonus. I can certainly deal with any OEM knobs I have seen on a reputable manufacturer instrument. Give me a handful of radio knobs from the '20s, '30s, and 40s, and those puppies are dang sure going on something!
