Straight bit vs slot cutter?

I just went for straight to slot cutter and may be going back to straight again.

I have used and still use….

Sommerfeld slot cutter set.  http://sommerfeldtools.com/professional-equipment-and-tools/router-bits-and-sets/router-bit-sets/12-pc-three-wing-slot-cutting-set

CMT tounge and groove set.  http://www.tool-home.com/products/catalog/product_info.php/manufacturers_id/131/products_id/17581

Both with great results.      On the Incra router table.
