To a large extent it depends upon what you're used to. Most people find
what they're used to to be easier than what they aren't. But humans are
very adaptable, it only takes a bit of practice to get used to doing things
a different way, whereupon they become easier. But you have to want to
practice new things, some people prefer to stick with what they know.

That assumes that you have enough visibility to be able to see distant
features, but that's sort of beside the point. The key factor about
following a GPS GOTO is that you *don't* have to walk in a straight line
toward it. This is something that many people fail to grasp when they first
start using a GPS, the natural temptation is to follow the arrow and walk in
a straight line.

But once you realise that you don't have to do that, and fully accept the
fact that the GPS arrow will always point toward your destination, no matter
how much you zig-zag, then you can experience the true freedom of using the
GOTO arrow. And that's what makes it easier, you don't walk in a straight
line, instead you just choose the path of least resistance. Provided the
arrow isn't pointing behind you, you'll eventually get there, without any of
the hassle of having to walk in a straight line, which is what compass use
encourages.

If you have a GPS, and a waypoint set at your destination, you can simply
read the bearing off the GPS, instead of taking it off the map. You can
recheck it periodically in case you drift off course. I've used this
technique when walking up a slope that was so steep that I wasn't moving
fast enough for the GPS to give me a proper direction. (Nowadays I can use
the compass feature if that happens, but I didn't have that in my old GPS.)
It's best to set the GPS to "magnetic" rather than "true north" if you want
to use it for this.

Or forgetting to add the magnetic variation, or subtracting instead of
adding, which is not so easily noticed. Not that the difference is much
these days.
