To some extent. It's really useful to have at least as much build capacity as capacity in your army camps. I have 4 level 6 camps so I have a troop capacity of 200. I have 3 barracks upgraded to level 7 and one upgraded to level 10.

It's nice to be able to queue 50 slots in each barracks to match the 4 camps.

After that I think you get some diminishing returns. Although, if you plan to use pekkas and dragons a lot it may be worth it to upgrade the rest.
