Obviosly a lot of these companies have some pros and cons.
Nintendo doesn't really develop Mature titles but are great with everybody type titles
Sony gives chances to art style games but lacks good advertising
Miccrosoft has huge advertising campaigns and has big budgets but doesnt give chances unless they think it will be successful
EA and Activision are pretty good with advertising but if you create something successful expect it to be an annual release.
Valve, Bethesda, EPIC Games, and Rockstar are probably the most quality publishers out of all of the multiplatform list in my opinion.
My honest opinion, I'd partner up with EPIC as they are talented, great with graphics, creative, and there games sell well. Plus going multiplatform would maximize profits.
