For Neve the best (closest to hardware) that I know of is the Voosteq Channel N...it's like $17 and puts the others to shame...
As far as API Pulsar Modulars is pretty darn close (MDN 450 or something like that I don't remember the name, I have it but not in front of me)...
And just to throw a wrench into the conversation a company that is really bad at a lot of things and quite good at a few others...the Antelope Audio VEQ 55A is dead on match to my actual API hardware preamps/EQ's...as much as I hate to recommend them...
not sure if it is the best but there are some videos check out the Softube British Class A
this plug will keep you busy it has a lot of stuff on it..I have heard guys say they like the drive from these Softube Neve Plugs
