I've found Boxer briefs to be great for all the same advantages mentioned above.
But Champion brand has worked well for me at about half the cost.
They are light, fit well, are very breathable, the waist band stays flat and they dry quickly.
Last July in New Mexico I put them on wet after washing them (and myself) and they were dry less than an hour later. But I can't say I know that'd work as well in other climates.
