Do you have a link to that theory craft you can provide if there's "a lot of" it you've seen? I've really mostly seen simulation differences in the threads which show 'in simulation' that CSD is better, but simulations are black boxes. It doesn't actually show the math behind the simulation.
Because I really have not done the math on these things myself and I don't really trust my own calculations being new to trying to figure these things out for myself, I would be interested in the source material.
I did find a theorycraft reference as to the actual damage boost the Chaotic gives in the WOWMB forum
Chaotic Skyflare Diamond - 9% Crit damage? - The Warlocks Den Forums
Although the chaotic gem says 3% extra damage, due to how the talents scale up the damage (double crit damage) the 3% is applied before the double damage not afterwards, so actually with the talent it's more than 3% extra damage.
It ends up being 209% increased damage on a crit with the meta gem instead of just 200% (or +9% not +6% as I was assuming above).
If that 9% extra happens 25% of the time (25% chance to crit), that's a pretty large boost or on average something like 2.25% (9% * 25% of the time) more damage over all. +25SP seems unlikely to give such a large overall increase in damage unless spell power is extremely low. Even as low as beginner Naxx10 gear @ 1500SP, +25SP is only a 1.6% increase in overall SP (Although I realize SP != DPS exactly). At Ulduar level starting gear at around 1800-2000SP, +25SP is a flat increase and yet the increase in damage by percent from Chaotic gem actually scales.
This idea appears supported by simulation in the EJ thread that was linked earlier in that the difference betweenb Beginner Naxx vs Beginner Ulduar gear between the Gems.
In Beginner Naxx gear, the CSD crit% bonus gives a boost of (50.37 - 32.63) 17.74 DPS over the +25SP gem. Contrast that in beginner Ulduar gear, the CSD gives a boost of (79.98 - 35.13) 44.85DPS. In essence also demonstrating the CSD scales with ability to do damage based on your base gear stats.
So I think the simulationcraft corroborates what I am attempting to show by math as to why CSD is better than +25SP, but I am not sure if someone else has written the math up in a way that is more correct than I have attempted to do.
