In short, they're walking nuclear death mobiles which are nearly indestructible and unbeatable in combat(unless your Snake,Raiden or a cyborg ninja) to regular infantry,AFVs and other forms artillery. So unless your gonna launch another nuke at it from a distance in the middle of the battlefield they're demonic weapons of destruction plus they can be mass produced and are highly portable but as you said Metal Gears get a decline in use and battle efficeincy because the cost and supplies to actually make one and also newer tech( like SOP and cyborg technology). The short answer is they can launch nukes ANYWHERE in the entire world and they're invisible to radars and so cannot be intercepted so once it launches your finished!
