On socket or wrenches I prefer 6 point. There is less of a chance of rounding the nut/bolt. A fine toothed ratchet and a 6 point socket will do it most times, but sometimes you have no choice but a 12 point.
I have both, but if I can I will go with the 6 point socket and/or wrenches.
You can use a 12pt tool on a 6pt fastener but not the other way around. As a home user (although I have 5 vehicles) I have both because there are certain 6pt fasteners that I refuse to risk rounding off.

I have both, but reach for the 6-point first. The 6 gets a better grip on a very tight or slightly rounded off (often go together) fastener. For a very tight spot, sometimes it is easier to guide and start a 12-point into place. And sometimes you have no choice because the fastener is 12-point.

I use both, I prefer 12PT. Some nuts just need that extra torque to release so out comes the breaker bar 6PT thicker to stand up to jumping up and down on. Tractors and loaders bolts/nuts get rusty quick. Chris
I prefer 6 point as almost everything I work on is weathered, rusted or butchered by a prior attempt to remove it. 6 point grip better, and are less likely to round over on a damaged nut or bolt head.
12 point are useful for positioning, especially with box end wrenches, and they can be used in a pinch for square nuts or bolts.
There are now 12 point bolts and nuts, but I haven't encountered any of those on my equipment yet.

"All the citizens of this land are of right freemen; they owe no allegiance to any class and should recognize no task-masters. Under the chart of their liberties, under the law of high heaven, they are free and without shackles on their limbs nor mortgages upon the fruits of their brain or muscles; they bow down before no prince, potentate, or sovereign, nor kiss the royal robes of any crowned head; they render homage only to their God and should pay tribute only to their Government. Such at least is the spirit of our institutions, the character of our written national compact."
