Plain maps are all you get in real vi, so people coming from that
background will use them by default. Some other reasons:

Making complex maps that can be tested piece by piece and then chained
together.

Making subroutine maps that can be called by other maps.

Making maps that are recursive.

Look at the toy macro sets that come with vim. Towers of Hanoi, eg:

" to set the height of the tower, change the digit in the following
" two lines to the height you want (select from 1 to 9)
map t 7
map! t 7

That's using a map as a variable. Then later in the macro set it gets used
like this:

"delete more than height-of-tower characters
map q tllD
