Depends where you live. In the city yeah. On country roads with no street lights though they are good.
I'm not sure that the difficulty of performing a trick is related to its utility, and it doesn't really make sense to compare the usefulness of high beams and foglamps since they are indicated in completely different situations. Foglamps are mounted low and are usually yellow and meant to illuminate the road surface in heavy fog. High beams are counterproductive in fog.
Not a hard trick since high beams are almost never needed. Only to tell people it's their turn to go at the 4-way. They're only marginally more useful than fog lights.
