I prefer to go alone, but my wife wants me to have a buddy along now that I'm over 60. Good idea really, there is always somebody who knows approx. where you are and will come and look for you or at worst, alert authorities if you don't show up due to injury or whatever.
As for the hunting itself I still want to be alone. Buddy can go wherever he wants, but I want to be alone. We'll arrange to meet back at the truck or camp or whatever, for lunch or at the end of the day. If either guy gets something, you can agree to find a way to meet if either hears shots or using walkie talkies, whatever it takes to share the work. Plus sharing gas at today's prices is beneficial.
If you are really new at hunting or outdoor exploration, yes, bring a friend. Even a non-hunting friend. That's much better than an unsafe partner. Avoid those types.
