^^^Again, EQs shape sound differently. I won't say any 1 is "better" necessarily, just different. Tons of tools in this craft can definitively be "better" beyond opinion. Mics, AD/DA converters, Pres, ect. Even when considering these things, other factors even the playing field, example, a $4,000 mic in an untreated room used by some idiot who thought he could buy quality with money vs. a $100 USB mic in a treated environment with an engineer who knows what he's doing.
With EQs it's different. The things that make one "better" are all going to be opinionated for the most part especially in the digital realm. They're easily emulated by software, and the only things I can think of that would make one "bad" fall in the hardware realm. Example being too noisy. I will say they're worth the money to a guy who wants to be more "hands on".
Even with compressors, I don't feel one can be "better", but there are day/night differences that make choosing hardware over software or even one software plug over another make sense. Channel strips with EQs, sure...but just EQ? Can't get worked up over that in 2014. If you got options with all the functionality you need, nothing more is needed. Some may just need 2 knobs("hi" & "lo") while others need 30 bands and Filters that can be adjusted, but as long as the EQ can do everything you want it to...I can't see "sound" being much of a factor unless something on it was programmed faulty. And even if it was...easy fix...go to any old other EQ you got mixed in your programs, lol.
