The 220386 has 16AA Missiles verse the others 24 (20386 has better AA so I guess depends on if you want quality verse quantity)
I believe 20386 has better Torps.
But the 20386 offers more utility for the navy over the 11356, that's why for a ship that's going to have a 4-5 Displacement when fully loaded it is lightly armed because it also serves a utility purpose.
the price the 20386 is almost twice the price of the corvettes 20380/20385, 11356, and is very close to the price of the frigate 22350, to which the 20386 is significantly inferior in its combat capabilities. (yes this is confirmed, this is why some Russian's opposed the class)
It's a better ship overall then the 11356 but if your building one of these you could just pay a bit extra and get a 22350.
