In 3.0 this was assumed to be on par with or better than Blizzard spam in terms of damage, but it has largely been ignored since Wrath launched. I'll do the calculations myself, but I need the exact coefficient splits for flamestrike and living bomb (in terms of dd vs. dot). The issue with the reticule size is largely overblown, in my experience.

For my gear level, and for a few specs, here's some raw numbers for burst AOE. These hold up fairly well as I vary gear within the "blue green" to "nax25" levels.
What I have not done is run the numbers for a fully talented deep frost blizzard, which I think is significantly better than the various frostfire type blizzards.
We'll use untalented arcane explosion spam as the baseline. So if a value is "1.25" it means "about 25% more damage than arcane explosion spam". Flamestrikes don't assume downranking for dot, and only assume 25% dot "uptime" if used as instant, 50% if used as "spam". You can do a bit better than that in real play in a sustained aoe situation, but I did these calculations for bursts of 6-10 seconds, looking for spike aoe damage, not sustained dps.
One odd thing is that frost nova actually does better DPS at current gear scaling than arcane explosion for less mana and also helps with blast wave knockback, so I included it in the "nonfirestarter spec" bursts for comparison. Likewise on the frostfire I show a "shatter blizzard" spec vs the more normal spec without it, where you spend those points on mana efficiency/threat. These are rough estimates, gear dependent but should give a ballpark idea. 1.78 doesn't mean "1.78" it means "in the ballpark of 2/3 to 4/5 more damage depending on gear. The error bars are large, but the relative placements are probably right.
Spec1: Generic arcane/fire. 18/53/0 fire utility talents moved to aoe talents
assumes no torment of weak uptime, about 50% uptime on arcane focus
1.05 Arcane explosion spam
2.33 dragon breath/firestarter flamestrike/blast wave/firestarter flamestrike
1.78 dragon breath/frost nova/blast wave/cone of cold
1.34 flamestrike spam (3 seconds per cast, no downranking)
0.99 blizzard spam.
Spec2: Generic frostfire. fire utility talents moved to aoe talents, shatter needs another talent point for imp blizzard
1.00 Arcane explosion spam
2.33 dragon breath/firestarter flamestrike/blast wave/firestarter flamestrike
2.10 dragon breath/frost nova/blast wave/cone of cold (assumes shatter)
2.00 dragon breath/frost nova/blast wave/cone of cold (no shatter)
1.30 flamestrike spam (3 seconds per cast, no downranking)
1.30 blizzard with shatter talents
1.24 blizzard without shatter talents
The above numbers also assume you've figured out how to target flamestrikes efficiently in the gcd's or during
cast time. I've found that with practice this is pretty efficient and mob motion is predictable so it's not a horrible
assumption, but you can shave a bit of the top burst rotation if you don't believe that assumption.
So the takeaway is if you are arcane/fire, arcane explosion is better for sustained aoe than blizzard, but probably your best result is taken with flamestrike and downranked flamestrike, alternating between rank 8 and rank 9. That kind of rotation and also assuming full dot uptime, not half, would probably put it into the 1.5ish range on the scale. For burst the firestarter talent is an extremely well spent two talent points.
If you are frostfire, you'll probably never use arcane explosion, and flamestrike is only a marginal increase over non-shatter blizzard, and similar to shatter blizzard. Which means you probably won't use much except blizzard unless you need mobile AOE or have a reason to desire a 3 second windup before the spell drops....but flamstrike is still a solid alternative in the rare circumstances when it's convenient. Again, if you want burst aoe, you're probably best off spending all four points but because your frost nova and cone of cold are better, the gap isn't as large between "With firestarter" and "without firestarter".
None of this considers mana burn. For the record, flamestrike and blizzard are about twice as mana efficient as arcane explosion spam for either arcane/fire or frostfire, largely because of the mana reduction talents in those trees not applying to arcane. The burst aoe rotation is only sligthly cheaper than arcane explosion spam - the base costs on those spells are pretty high. It's actually not a lot less efficient to do the blizzard or flamestrike spam than to just do a normal deep fire rotation (it is more expensive than a frostfire rotation). This assumes enough targets to fairly reliably get a crit on each tic for blizzard and on the main blast for flamestrike to get moe payback, so 3-4 victims is ideal. Blizzard gets a lot less efficient if they don't hold still for 8 seconds, flamestrike does a bit better than reported if they stay on the small aoe for the full 8 sec.
You'll note I left living bomb out of the comparison. That's largely because it does identical damage for all specs consideed and is highly situational on whether it's useful at all. In the range of sub ten second burst I was looking at, it's essentially useless. In real play, I've used it in all of the scenarios and rotations, usually on a secondary target from the main dps focus target, so it would live long enough for the burst to go off.
