I know the manual says whatever comes first.. but I hear more and more people seem to follow hours only.. what do you follow?

I just did the first oil change on my 2016 900 Trail.. 330mi/21hr. Manual shows next oil change should be 50hr/500 miles. I will be at 500 miles WAAAAY before 50hr.. so do I wait or change it again right at 500? I just trail ride so no major abuse.
