I disagree slightly here. Low downtime means absolutely nothing if your kill and exp gain ratio is low as well. Sure, it may be a more engaging way to plow through one mob at a time without ever having to drink, seeing as how you're constantly doing something, but if it means you'll take 3-4 times longer to get things done, it's not very smart in the long run.
Fun gaming experience aside - and I do love leveling my plethora of alts without any hurry, the absolute most important thing in leveling is speed. If your entire goal - again putting the fun aside - is to gain a level, and gain several levels, then the best possible way is the fastest possible way, and let's face it, killing several mobs is always better than killing one mob.
Take the frost magi as an example. They're the most mana-efficient caster class and spec out there as far as single target leveling goes, or at least they have been in the past. However, if you compare a frost mage killing 1 mob at a time, to a frost mage AoE farming mobs 10 at a time, the fact that the mage has to drink after one AoE pack means little, when he's so much ahead in the XP ratio.
No, I don't think farming mobs is better than doing quests; quests have been proven time and again as being the absolute best way of leveling. However, there are times when killing several mobs at a time while doing a quest is an option, and a good one at that.
Leveling to ~50-60 these days shouldn't take any time at all, unless you're spending time staring at the scenery, and at those levels shadow simply blows smite spamming and discipline out of the water, no question.
Hell, the reality is, you can get to level 60 without spending a single talent point, and you can do it with your eyes closed.
