As i said, Upgraded M113 will be much more potent combat vehicle than Stryker.But Stryker is quite good police vehicle .You can easily equip M113 with the same C4I suite,OWS,armor atc, without problems with ride capabilities. M113 is far better maneuverable (pivot).Internal volume of M113 is greater , soldiers will not have problems get out as they had in Stryker wearing protective vests with armor plates. With today technologies is possible make tracked vehicle fast as wheeled one.Loudness is only issue if you not using rubber reinforced tracks.
Stryker MGS is totally unadequate for a mission,it is too heavy for ac-130,105mm M68A1 gun has too big recoil, wehicle is not capable of accurate fire on the move.M8 AGS would be far better with much lower costs.
