Both displays are doing very well, but it is very hard to make good
pictures. It depends very much on the angle. You can read both
displays very well in direct sunlight, but you might have to turn them
slightly.

The Streak turns into a mirror quickly in some sun angles, but you can
still focus your eyes on the screen (within limits). At the same
angle, the Altair is not doing significantly better: instead of seeing
a small mirror image, you can see the sun spotlight all over the
screen, making it unreadable as a whole.
