IMO ICS sig 551 is the best minus one thing, their mags blow, bad feeding issues when i got mine, i have herd ics is coming out with mid caps for them, but for internals and full metal ics is my choice for sigs..some tm mags are compatable some need to be modded but it is a easy task to do..if you go with a 552 you run in to battery problems, not much space for a good size battery, with the 551 you have lots of room.
