Conq or Sin for PVP

[Tony82]

I am torn between creating a conq or sin. My past characters that I did enjoy and invest time into are my barb and demo. I want a conq because they're cool, flashy, and can be great in the right hands. I want a sin because they're also cool, flashy, and can be great in the right hands. I am not opposed to DPS or tank roles in PvE content and I know all classes are fine in PvE, but I also am under the understanding both are good for PvP. It's tough because this time around I do not have as much time to invest into a character, so I'm also trying to consider which will be a better return on my time investment. What do you guys think?

Conq 2h if you play from EU (ping 200+ ms).
Conq Carnage if your ping is around 150 ms.
Sin if you are a lucky American dude

That's all.
