We are going to pull up our existing hardwood, tile, and carpet downstairs and replace it with a high end cherry.  A flooring specialist who is highly recommended came out to our house to measure today.  I had told him what we are going to use, and he brought a similar alternative for us to look at.  Our first choice is a 3/4" prefinished solid Brazillian cherry, the alternative he brought was a 5/8" solid cherry.  Regardless, we are going to spend a lot of money, but he says the 5/8" stuff is just as good and is @ $4.00 less psf.  I don't know about that.  Our first choice is also 3&1/2" wide, which I think looks better, vs. 3" for the other stuff.  My inclination is to buy what we want because it's going to be expensive regardless, and I think I might regret not getting exactly what we want, but man...it is an expensive pill to swallow.  I would appreciate any insight you guys might have.

I'd go with the Jatoba (Brazilian Cherry).
The stuff I've worked with is much harder than cherry and should wear better.

My bad, it is actually cabreuva (mahogany?) if that makes a difference.

Have you thought of doing it yourself ?  I've done-it-myself & hired pros.  The pre-finished (Bruce) that I installed was bevel-edged which hides a lot of "sins" but then I've got a fair amount of woodworking experience anyway. We have 2-1/4" wide varnished oak now, and I'm guessing it is original from 1926. We may not get another sanding down to bare wood because of how thin it is where the top "groove" meets the "tongue" of the adjacent piece. I'd think the 3/4" you selected may last a bit longer because of being able to be sanded one more time. Then again, if you don't  think your pro has some hidden agenda ... I'd trust his advice OR get a 2nd opinion from another pro. Sometimes, if your installer is familiar with a certain product, they'll do a bit better job. That's my 2c.
Good luck.   Stay safe
