Ask WoW Insider: What's up with bar AddOns?

It's Friday, folks, which means it's time for our weekly edition of Ask WoW Insider. Last week we looked at the best way to power level alts, and this week we turn our attention to a question from Spyke about AddOns:
Ok, my question is simple. I am a huge proponent of addons. When my friend first introduced me to them I gobbled them up, first trying out packages and then finally just searching around sites and downloading them individually. My question however is this, is there really a need for bar modification addons or is it pretty much player preference? I have tried using them a couple of times but didn't feel like spending the time required to configure them when I was happy with the default UI bars. Any answers would be appreciated.
We've talked about Bongos, CyCircled, FlexBar and other bar mods before at WoW Insider, but Spyke gives us an excuse to ask you all: what bar mod(s) do you use, and why? Do you feel like it's game-breaking to live without one? If you've tried several, which is your favorite?

Send us your questions for next week to ask AT wowinsider DOT com. Get on it!
