It depends on the tolerances you are manufacturing and inspecting.
Calipers are a fair all around tool, however, due to the large area of
the measuring surface, some averaging occurs. Calipers are also only
good around the periphery of the board. Comparators are a fine tool,
but rather expensive. There are "deep Throat" micrometers with radiused
tips that are very effective in measuring the middle of boards. It
really depends on your application. I hope that some of these ideas
help you in your measuring concerns.
