As a German-o-phile type player (albeit with 6 winning Soviet campaigns to my name), the Rifle Brigades are really good defenders once they get over 4-ish thousand men. They can't take new ground well because of the brigade penalty to movement, but they hold lines well.
When they are shells (under 1.5-ish thousand men), they soak up German movement points to attack just as well as a corps would, so it's often useful to put shell brigades in defense that have no hope of Held results, but will still cause the Germans to have to attack them. Bear in mind that in the latest patch, lone brigades are subject to route/shatter more, but where shell brigades are concerned in 1941, this is no big deal. Losing half of nothing (in terms of long-term manpower) is still nothing. You do, however, need to know how to play the Admin Point game in terms of not losing so many units that you are unable to rebuild an army later.
