Culled from a single forum thread, I'm biased but I'll bet these folks (from a place with more than a fair share of industry pros) would agree ours sound better but definitely save $20 if that's more important and yes, YMMV:
"Very impressed IK. Never heard an itb eq do this kinda stuff before."
"Ohhh my goodness [sic] it sounds so right on bas [sic], drums, guitars etc. that its almost stupid"
"these sound great"
"they sound is amazing"
"Actually i like the eq on the plugin much better than the hardware"
"I actually prefer the 'air' the 73 added more than my Clariphonic HW unit....which nothing has beat yet."
"Must agree that these 2 IK Eq's are top notch and for ITB Eq, they're now my go to."
"Great job! I'm replacing my old V-Series with them in some sessions and there is a marked improvement"
"Great work IK. Every plugin coming better and better.. Those two are amazing."
"Really rich, meaty EQ. The Q is amazing when used with the input drive... the lows, low-mids and mids + input drive ... holy smokes."
"These guys do have a legacy, like it or not."
"...this IK 1073 works like magic on distorted guitars"
"...comparing to AlexB's Nebula 1073.... and trust me this is THE MOMENT I've been waiting for... I think it may be beat."
"These EQ's are amazing!"
"I 100% concur with your rave reviews. These things are going to replace Nebula for at least Neve, if not for the processing of EQing altogether."
"I am not going discredit other people opinion - but usually it's a hype with these products. At least for me. Well this one isn't just hype. I will probably buy it. It does have such nice weight and pleasant tone. Really it is special. Wow."
"very impressive plugins, the most musical and organic 1073/1081 emulation up to date"
"I'm under the impression that once again, ik multimedia just kick the competitor asses!"
"there is a tone and sheen added to them which really speak about these EQs. Really silky smooth and full of weight."
"Best IK release to date IMHO."
"Wow, I'm speachless. The EQ73 sounds surprisingly good, reminds me of how good the Comp 670 is (until now it was, in my opinion, the best thing in T-RackS). I like it better than AlexB 73eQ for Nebula, no doubt."
"You managed to make the best plugin EQs ITB ever IMHO. I am speechless. These two wipe the floor even with Nebula renditions. They make other Neve clones sound like joke. And thank you for avoiding the concentric knobs as these make no sense ITB, just do the handling cumbersome. This is by faaaar your best release which highly surpasses everything UAD has ever done in the EQ land. These do have a weight that is expected, do have silky smooth highs and superb midrange. I don't know how you did it, but you definitely did. Benchmark for all the other EQs from now on IMHO."
"IK has taken the 1073 crown in my book."
