I just wondered how would you define: bad donor, average donor, and good donor? thanks!

my subjetive impression of volume, density, shaft thickness 

I understand that there are plenty of devices to evaluate donor area such as K-bot or regular dermatoscopy. I use them rarely.

does that mean its not a true 0.75 most likely

That is correct. However this is not by their fault. Most manufacturers claim they're selling a .75 diameter punch when it is really not this diameter. Or they claim this is the "internal diameter" when what really matter is the external diameter (which will determine the hole size).

There is an article by Brazilian HT surgeon Dr Mauro Speranzini where he compares the diameter of the most popular manufacturers of HT instruments and found out that only Trivellini and WAW punches had the exactly diameter they claimed to have. I'll try to find it and put the link here.
