Prefered ieee libraries?

I'm at a critical point before I build up too much code.

Which is the more preferred/forward thinking approach?

library IEEE;
use ieee.std_logic_1164.all;
use ieee.std_logic_arith.all;
use ieee.std_logic_unsigned.all;
-- then used to_integer, etc.

or

library IEEE;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
-- then use conv_integer, etc.

Thanks! Hope this isn't a question of religion...
