Which of the two holds up better to wear and tear?

I've noticed patina seems to rub off from just a few chops into wood and was wondering if acid washing is any better.

Acid washing is used to create a patina, so I am not sure where you are going with this.
 
Anything acidic will cause a patina. Will you be using it for food prep/game processing at all? If so, use a vinegar patina. If you are worried about the patina coming off, and don't plan on using it for food prep, you can get it blued or get it duracoated.

I don't know of any preventative coating that won't do this. The good news is that rust will have a hard time forming in those spots because it will rub off just like the patina. ;) And if it does form, just rub it off with something. Horse tail and usnea(old mans beard) work well. Unless it's a food knife, rust really isn't something I worry about too much. People seem to have it in their head that a knife will fall apart if a hint of rust is on it. Which it just doesn't.
 
Acid washing etches the steal, rather than just forcing a patina. At least I thought? Having patina and acid washed blades in front of me it's night and day difference.
 
You should read up on different types of acid. Vinegar is an acetic acid and differs greatly from etching acid solutions. Dipping your knife in vinegar is not the same thing as dipping your knife in etching solution.
