You mean if comparing to a string constant, or generally?
Generally that depends on context and data; try the following
variants (Unix environment) and compare the output...

$ printf "%10s\n" 5 | awk -v num=5 '$0==num'
Output: 5

$ printf "%10s\n" 5 | awk -v num=5 '$0""==num'
Output: (none - no match)

$ printf "%10s\n" 5 | awk -v num=5 '$0""=="         "num'
Output: 5
