I have the CV 180 APO and Mamiya 200 APO and have owned the 180/2.8 and 180/2 APOs from Leica and tested all but one of the lenses Samuli mentioned.
All a very good within any specific design constraints (e.g. 180/3.4 for infinity), but the CV and the ergonomically-challenged Mamiya are two of the THE best 180-200mm lenses I have ever used -- at any price point. They both play easily with their more costly brethren. The CV SL APOs were very much initially under-priced given their performance (although that is coming to an end fast) and the Mamiya 200/APO cost something like $3000 when new.
I think you\'re biggest issue is going to be picking a winner from a collection of same.
