THERE IS NO MAGIC SOLUTION TO THIS QUESTION!!!!!!!!!!!!
Each rifle will have it's own ammo preference. The only way you will know what yours likes is to try several(worst case scenario=many)brands/bullet weights/bullet types. The selection is large in the 30/06. Start out with common stuff like Hornady Custom, Remington Corelokt, or Federal. Personally, I've never had acceptable results from Winchester Super X but have from the Supreme. If you don't find a useable combination, keep trying.
For deer hunting, my choices are 150-165 grain pointed soft point or polymer tipped bullets.
I shoot a lot more handloads than factory loaded ammo but for the last 7-8 years, my deer hunting ammo for the 30/06 has been old stock Ultramax commercial reloaded 165 grain Ballistic Tips. Absolute deer hammering stuff.
