High solid epoxy vs polyurethane flooring....wet processing

Good Morning....  Hope this communication finds everyone well.
 
We are in the planning stages of various facility renovation projects, floors are one of the main areas of the renovation project.  We have several contractor's quotes, some quotes are for epoxy and some are for polyutherane.   When asked each contractor can sing the praises of whichever type of flooring that they have quoted.  I have done web searches and read articles all of which present the pros / cons for each type, however, I would like to find specific specifications for each type of flooring material versus the subjective "high resistance" or "long-lasting" terminology that I am finding.  Can anyone direct me to where I might locate this information?   I would also be interested in any experiences or advice the IFSQN members could offer.  We are a fruit/vegetable processor and processing in a wet environment.  
 
Thanks in advance for the help...

I like urethane as it has some "give."  Epoxies in my experience require very good prep and are brittle. i.e. can flake when damaged.

Some brands of floor I have used are "Stonehard" "Ucrete" and epoxy paints.  the paints have to be renewed every year, but I don't have time to prepare the floor to do a better urethane coating.

good luck.
