I enjoy the Random BG queue, the bonus honor is nice and the variety keeps things fun and interesting. The only BG I really don't care for is Strand of the Ancients, so overall I've always found it to be a safe bet.

I also tried a Wintergrasp the other day, it wasn't very exciting as it was essentially my team and 6 other people (most of whom were under level 85), but it turned out to be decent honor. I was able to complete four quests at 24 honor each, and another 100 or so honor from victory (we had all the bases capped, so could be bonus honor).
