RC bottles and opaque liquid or clear liquid

[Atom1]

They come both ways. Some are clear and some are opaque.
I know pharma is better but let's face it, lots of people test with RC's.
RC's have become a total crap shoot
Question for those who have experience with both clear and opaque liquids:
Which one is better? Any difference noted?
Does clear come up ineffective more often than opaque based on experience?

That doesn't matter at all.
