Personally I find the Srixon Tour Yellow to be awesome. So very easy to spot in the air and/or on the ground. The only time I have a hard time seeing it is in the fall with leaves of similar colors. Aside from that, I can track them in the air without a problem, or spot them in the fairway/short rough/etc from a distance without much trouble.
The Srixon Z-Star XV in Tour Yellow is my favorite ball thus far. I've gotten so used to them, I have a hard time playing white balls anymore.
As for being hackish/scrubbish? I've had several people make fun of it, or crack jokes, but I couldn't care less. The only annoying thing about using them, is if someone a little new to the game is playing with you (or just doesn't know about them)...they often think I'm playing range balls and offer every top flite or pinnacle they find to me.
