DL Elites (Silver/Gold/Plat) have a 2 bag 70 lbs allowance. For me, this is a huge benefit of DL Silver. When traveling in First or BE that allowance is 3 bags 70 lbs.

A comparison of DL Silver to CO Silver (DL Silver looks better 
)
DL
Silver advantages/disadvantages over CO
Silver:
Advantages of DL Silver (compared to CO Silver)
-DL offers SkyTeam Elite, which is more valuable that *S that CO Silvers get.
-Bags are 70 lbs for DL Silvers not 50 like with CO. <--big deal for me.
-Companion upgrades permitted on K+ fares, whereas CO Silvers do not get companion upgrades.
-Can select priority seating
including Exit rows (and CO Silvers cannot select Exit Rows on CO) <--- Huge difference.
Disadvantages of DL Silver (compared to CO Silver)
-DL Silvers traveling in Economy Class do not get access to the priority security line, whereas CO Silvers do.
All other benefits between DL and CO seem to be comparable.
