Here's a tantalising opener if I've read one:
Carl Zeiss ZM lenses is an amazing phenomenon is (sic) photography: despite their excellent quality and ergonomics, most Leica M shooters do not even know about them. The main reason for their relatively low popularity, besides snobbish attitude of “those with the best glass in the world”, is that at any focal length Leica optics surpassed Zeiss ZM lenses in speed. That is until now…
This review, written by DPReview forum member, Irakly Shanidze, is salted with well thought-out images (and the above freakish thing); and though it doesn't prove anything intrinsically different, or better, about the Zeiss, it is a worthwhile read.

Assuming that tistory nailed focus in this comparo, the Samyang 135mm f/2,0 looks to be pretty damn sharp.

One of Rangefinder Forum's most helpful contributors, jonmanjiro, in 2013, posted a lovely comparison of four lenses:
Leica Summilux 35 FLE
Voigtländer M Nokton 35/1,4 MC
Voigtländer M Nokton 35/1,4 SC
Canono LTM 35/1,5
As you can see, although many decades newer, the Noktons appear to be cut from a very similar cloth to the classic -- and much more expensive -- Canon lens. The Summilux produces noticeably smoother bokeh. I am a long-time fan of the Canon LTM 35/2, about which I wrote at length. Later last year, I sold it to a collector because its aperture blades were in poor repair and I repairing them is costly, and difficult.
In its stead I purchased the Canon LTM 35/1,5 about which I will be writing soon.
The above Rangefinder Forum link comes from a reader named Adam, with whom I've been communicating since October of last year. Thank you Adam.

And evidently, calling out Fujifilm for this omission (the MCEX-16 tube goes for 99$ USD at BH Photo), qualifies as a rant, and is trollish.
The lesson, from Fujifilm fanboys, is that Fujifilm can do no wrong.
