Blackberry Curve or Moto Q Global?

Okay, so don't get me wrong, I am a faithful user of Blackberry. I have the 8700c right now, and it's practically my life. But I need a more updated phone, and I plan on getting one for my birthday this July.
I've read a lot of good reviews for both the Moto Q and the Curve, but am still undecided. Texting, internet, a camera with flash, memo pad, and conference calling are all a must.
So far, the only con I see for the Q is that I already have a Blackberry service plan with AT&T, and it would be more convenient to keep it instead of switching to another plan.

Help, anyone? Which phone is better for my needs (texting, internet, a camera with flash, memo pad, and conference calling)?

Answers would be especially appreciated from anyone who has owned both a Blackberry and a Moto Q, for fair objectivism from both sides. Thanks!

Well hey, I've owned both. Currently using the Curve 8330 through Verizon with the 3G technology. The MotoQ uses Windows OS and you couldn't pay me to go back to that. It was slow, choppy, and the Motorola brand completely disappointed me for its fifth and final time with the Q. No more. The BB Curve, thus far, has been great. The keys are small but it's a super light phone with great personalization, you can't beat that trackball, it has excellent features (as you well know), and you're already set to go for another BB with the plan. Oh and I've been told that the voice quality is vastly superior to my previous cell which was a flip phone LG. So that's saying something!
