I'm more entitled to believe prime Hiruzen is about equal to base Hashirama. Hashirama would more likely need to use Sage Mode in order to defeat prime Hiruzen. This is my personal opinion based off of what we've seen of old Hiruzen and going with the best approach of assuming his prowess in prime using logical thinking.
