If you had to buy one type of ammo for 10 different .22lrs, what would you choose to give the best mix of accuracy and reliability? I'm leaving cost out since that's very subjective. Ignoring higher priced match ammo, and considering it will be used for paper punching, hunting, varmint control, and whatever else people use .22s for.
When I go out to try a new rifle, I keep finding that mini-mags always function, always shoot well, and don't break the bank. I know each rifle has its preferred ammo, but I've never seen one that flat out hated MMs.
Maybe call it your desert island ammo.
