Snorlax: bad IVs, perfect moves
The only Snorlax with good IVs I have came from a 10k egg with Lick + Body Slam and 78% IV. I chose to power him up to level 30 (had to walk him for a bit) and now I'm really happy with him as both an attacker and especially as a defender - despite the suboptimal quick move, he still does better than any other mon with that.
The perfect defensive moveset for a Snorlax is widely regarded to be Zen Headbutt + Body Slam. I was lucky enough to catch two wild ones with that moveset, but unfortunately they both have terrible IVs. Here are their stats:
1628 CP (lvl 19), 27% IV (STA 6, ATK 0, DEF 6)
896 CP (lvl 10), 38% IV (STA 0, ATK 10, DEF 7)
Considering that IVs are pretty overrated especially on a mon like Snorlax, as they have a very marginal impact on his already amazing stats, would any of these two be worth powering up anyway? They'd still reach really high CP and be perfectly fine at the top of gyms in my area.
On a sidenote, I also have another one with Lick + Body Slam, at 2207 CP and 36% IVs, but I was thinking of keeping that one as a generalist attacker.

Some week ago I caught a wild 1900 CP Snorlax with ZH/BS, 40% IVs.
I've powered it up to 2702 CP (level 30.5 if I recall correctly), and I had to walk for each candy, since I've never hatched a Snorlax. I think it was worth every candy and the dust, as he is my second best defender after my bigger Snorlax.
Hope that helps.
Use a CP calculator to see what CP the lvl 19 Snorlax will be at level 30. Then figure out if that is an acceptable CP for your local gyms (I am guessing it will be). Snorlax is mostly a deterrent, so ultimately the moves and IVs won't matter too much.
Regarding the 2207 one, do you need a generalist attacker? I never use Snorlax on offense, but I also have strong attackers of every type. If you have multiple Vaporeons, you don't need a Snorlax for attacking.
It'd reach 2571 CP, which is not top tier for a Snorlax but still very high and really good for gyms.
And regarding the 2207, I probably don't "need" a generalist attacker but I really enjoy using him. Of course Vaporeon would do the job as always but on offense I prefer to keep things diverse and have a little fun.
Not worth the dust and the candies. Be patient.
Iv does have a huge impact on CP. With such low IV Snorlax will even be dominated CPwise by a high IV Vaporeon and Blissey.
Although ending up being a great defender, you will have move and more trouble finding a spot for him in a gym like a good Lapras. The difference being you can get a way better Snorlax while you cant take Lapras over 3000CP
IVs may be slightly overrated, but to say "especially with a mon like Snorlax" is completely incorrect. IVs are especially important with a mon like Snorlax because of his high maximum CP, and the way CP scales at higher levels -- IVs are arguably most important to pokemon like Dragonite, Snorlax, Vaporeon, Rhydon, etc.
I wouldn't waste the precious candy / dust powering up a Snorlax with bad IVs.
I would revise your statement to say "IVs are especially important for defending pokemon when you're competing for gym placement." It's only when you're trying to land a secure spot in a gym where the lowest defender has a CP of 2600 that you need every additional IV point you can get.
From a battle performance standpoint meanwhile, IVs have less overall effect on pokemon with the highest base stats because the IVs make up a smaller proportion of the pokemon's total stats (for example, an ATK IV of 15 on a pokemon with a total ATK value of 60 is 25%, but it would only be 10% of a pokemon with a total ATK of 150).
