TCB, for linear navigation the $nextpage/$previouspage is great, although it needs some safeguards like if $currentpage = 1 then there isn't a $previouspage.

For non-linear navigation, like a content list, it doesn't work because you can't jump from page 1 to page 3.
My second suggestion ( [ page=x ] [ /page ] ) is way much better for that and it also works fine for linear navigation, not to mention that it must be 10x easier to implement.
