What is lambda factor in Zambuto mirrors and what reflectivity?
Orion UK have 97% reflectivity and 1/10 lambda best mirrors to offer!

My Discovery is noticeably better than a buddy's Orion. However, I don't have any illusions about it being of Zambuto's quality.

If you have a chance to get a Carl Zambuto mirror and you can afford one, then just do it. You'll be in possession of a mirror from one of the world's finest makers.
There are other superb mirror makers, but I don't think there are any commercial makers that are better.
The other 2 you mention are decent mirror-making companies, but not in the same tier of makers as Zambuto.

Here is the only Rohr test on a Zambuto that I could find, looks pretty darn good to me. Of course this is only a 10" f6 but all of his mirrors are made to the same level of perfection.

I would be careful with the "97% reflectivity" thing, which speaks to the coating and not the mirror. In addition, there is ongoing debate about what kind of coating is best, and it may be that the coating with the highest initial reflectivity ends up NOT being the best after exposure to the environment. Finally, all claims like "1/10 lambda" are imprecise and ambiguous. The only test that you can 100% trust is what you experience when viewing with the optic, which is why I believe that Zambuto doesn't mess with these kinds of numbers at all. His reputation and past performance carries more weight than loosey-goosey numbers.

Beat me to it , it's worth looking into because normally there is a 9 to 12 month waiting list for a world class performing zambuto mirror.

If I were buying a new telescope, I would go either with a Zambutto mirror, or a Lockwood, (if I wanted a mirror faster than F4.) I agree spending the extra money for premium optics.
