Highly recommend the 1073 from UAD. Other emulations do not give you the further flexibility of UAD's Unison technology which also gives you access to the 1073 pre-amp, et. al., when recording through the Apollo.. I record most everything guitar, drums, bass or vocals, these days through the 1073 on my UAD Apollo. Really great plug. If I could only keep 1 of my UAD plugins I would keep the 1073. In comparison, I have the Waves Neve stuff, the V-Series EQ and never use them. Also tried the Scheps 1073 and I don't think it even comes close to the UAD plug. I am a fan of Waves too, so not knocking them. Their SSL stuff is pretty amazing as are many of their other plugs...Just very pleased with the UAD 1073. I have seen it on sale for $99 on the UAD store. Hope this is helpful.
Here is a nice comparison and overview of the Neve 1073 by Pro Tools Expert.
