Let's start a fight. 
I am unanimous in the following...
Nothing says, "I have no imagination and can't afford a plant" quite like a mulch bed.
I will suggest that you should never see the mulch (and weeds will never see the sun) in a properly planted flower garden bed. I will also suggest that the only weeding necessary is done with a garden edger.
Finally... any ground cover... even grass... is to be preferred to mulch.
Your turn.
