Lightning Bolt is long range and hits each target in its path for 15d3+45 (60 - 90 base) with a 50% chance to fork (double strike) and a reflex save for half. 364 - 546 non-crit / 1002 - 1503 crit

Fireball is normal range area effect 15d3+45 (60 - 90 base) with a reflex save for half. 364 - 546 non-crit / 1002 - 1503 crit
Frost Lance is long range single target 4d5+20 per lance with a maximum of 3 lances (+MCL does not increase number of lances) (24 - 40 base) with a fortitude save for half. 145 - 243 non-crit / 400 - 668 crit per lance
Opinion -
Lightning Bolt, Acid Blast and Fireball all have the same damage. Acid Blast seems to have a smaller area of effect than Fireball and will not break down doors like Fireball will. Lightning Bolt has the limitation of only hitting targets in a straight line but the benefit of 50% double strike chance makes up for that limitation. The deciding factor here is that you get these SLAs at level 18, when Fire has lost a lot of its usefulness due to immunities. I'd rank Lightning Bolt first, Acid Blast second and Fireball third for the T3 SLAs.
Frost Lance has a few problems. Yes, it does target Fortitude as it's save, which means it cannot be evaded and that is all well and good. The problem is that the number of lances does not increase past 3, limiting damage. Also each lance has its own crit roll, making it that much more difficult to attain max damage on a single target. It's also the only single target SLA in this tier and yet is not as good as Acid's T2 single target SLA. The weakest of the T3 SLAs by a fair margin.
Please bear in mind that my analysis is just my opinion, based on the way I value spells for my play style. You should not determine which Savant is the best for you by the SLAs alone, there is so much more to playing a savant then the SLAs.
I just wanted to write this out to see it in text, it helps me think about the spells and the choices that I make for my Sorcerer. I hope that some found it useful or informative.
I also hope that my math is correct and put a
huge disclaimer on that part of the post!
Always keep in mind that damage numbers are subject to other factors, such as resistances, saves, immunities, how you are geared, if you have a clickie running etc etc.
Thanks for reading!
