bathtub overflow configuration?

On the new waste and overflow drain that I am installing there are 3 possible configurations (direct, indirect down, and indirect rear). I am installing new dwv lines to the main stack so I can place the trap below in any location (open basement) so it is possible for me to use either the 'direct' or the 'indirect down' configuration.
Is there one that performs better than the other? It would seem to me that the 'direct' would be preferable as the water is going directly down to the trap and out as opposed to horizontal and then down to the trap.
Thanks in advance for all your help and advice!

If you get a clog, the most common way to snake a tub drain is to go through the overflow. This would only work with the indirect configuration. On most drains, you can't get the grid out of the drain without lots of trouble, but the overflow cap usually comes off easily.

Thanks.
The p-trap for the tub in the basement has a clean-out in it - does that matter?
