Both links can be usefull..
Its hard to tell you what the differences are that matter for you...
In short: DH5a is a general strain for cloning and blue white screening
BL21 is more for protein expression, it lacks certain proteases.
If you don't know it, then ask it! Better to ask and look foolish to some than not ask and stay stupid.
