They did! You can find a lot of engaging reviews here: If you have also read the rest of the blog, you have found other comparisons.

What's fundamental for Apple can be less important for Mac users, but is still worth mentioning. They say: 'if the first impression is negative, there will be no second impression'. It's well known that Apple has always cared a lot about first impressions. Just to open the program a whole order of magnitude. One of them is 10 times faster than the other. The first impression arrives when you launch the two programs. They belong, however, to the second impression. The more I see them, the more I hate them.

There are 5 omnipresent green handles to remind it and they are something I can hardly bear.

Even if you always populate it with a single spectrum, you are still facing the container concept. The MestreNova document is not a spectrum, but a container. MestreNova is much more usable, most of the problems have been fixed but the philosophy remains the same and I'll never like it. Last year I explained in detail that I didn't like the old Mestre-C. I simply wanted to demonstrate that I am the most biased source of information that you can find. How much dependable am I for you? Don't get me wrong, both products are so nice and stable and offer such a wonderful customer support that there is no concern of going out of business. If Mestrelab goes out of business, I go out of business as well.

Why should people read such a book when both programs can be downloaded and tested in less time? The truth why I can't write that book is that I am too much involved, it's so dangerous. If I start writing, I could write a book, like Rodgers and Hart. Something fascinating for me but no other human being can stand a whole day listening to it. If I start speaking about the difference between iNMR and MNova, I can go on for a whole day, telling you the whole story and philosophy of both. People keep asking me which program to buy for the Mac: iNMR or MestreNova? There are many other alternatives (NMRPipe, Jeol Delta, NMR Notebook, NUTS, VNMRJ plus, in the future, TopSpin and SpinWorks) for Mac OS X, but the first two products are so far ahead of competition that you must be eccentric or masochist to even consider something different.
