|Sram PC 89R. Best 9 speed chain made.
a 21 is fine for a flat crit.. but if your crit has a big hill, you may want a 25... depends on the course.

|I like the Shimano branded chains because the side plates bulge outward which helps shifting. Tried a flat plate chain on my last bike and could not make it shift as well as with a Shimano chain.
Both Ultegra and DA chains are fine. I don't think DA is worth the extra cost but if you find one on sale...go for it.
Just my $0.02

|What do you mean by best? Most durable? Cheapest? Best shifting? Quietest? Lightest?
I've switched from Shimano to Sram chains. I never was that crazy about the Shimano connecting pins. The Sram Powerlink is a no-brainer. Makes regular maintenance easy. Whatever you choose, be meticulous about cleaning and lubrication, and replace it every couple thousand miles. Chains are cheap. Even the most expensive chain is one of the cheapest components on your bike. Put a new one on if you notice shifting degrades and before you wear out the cassette or chainrings.
Cassette choice for a criterium? Depends if you're riding the typical flat 4 corners in the industrial park or racing Nevada City. Heck, I rode most crits in my day with a 13-18 6-speed freewheel. If it's flat, a 12-21 is plenty. If you have to get off the big ring with a 12-21 on a flat course, you're going to be off the back anyway. For something with a significant hill you might need a 23 or 25 to minimize double shifts.

|SRAM makes good chains that seem to work fine on Shimano drivetrain.
Just make sure you have enough of a low gear so you don't have to shift to your small ring. Also figure that in the big ring the big cog won't be used because of the crossover, so your 12-21 is really a 12-19. I customize the cassette for each crit depending on the difficulty of the hills.
