the sopmod will have much more aftermarket ability. Not only is the ICS a slightly proprietary mechbox design (not a huge deal considering most of the mechbox internals are standard anyways) but an M4 is an M4. Anything can be swapped out with different after market parts ie ris, grips, stocks barrel etc. The sig has much more limited external upgrades.
