Brakes off, unless you really really can't roll at all.
Learned this while landing on a large pad at Max AUW. Building near pad blanked my headwind low final, decreasing performance shear, tried to slow it down with full intermediate, landed about 12 deg nose up (15max) about 15kts ground speed with brakes on. Couple chirps and then the nose really wanted to come down.
Hindsight, leave brakes on would have rolled very little.
Of course totally preventable if I realized what was going on earlier, but sometimes you don't realize these things. Brakes off gives you a few more options.

Here's a thought for everyone. When Winnipeg was flooding I was flying 6,000lb loads of sandbags from a muddy location to a distant dyke. Picked up load, wheels sank in mud. Trying to rip mains out of ground, I got very very close to dynamic rollover.
Question: Would the wheels have released more easily if the brakes were off?
