For healer:
power boon is 100% better than crit severity. Clearly crit severity gives you more healing power if you capped your crit healing chance at 50%. However, the only time healer fail to heal enough to keep someone alive is when your healing power fail to crit. If your healing power crit, the person will survive easily even with 15% less crit severity; If you fail to crit heal, players may die if your basic healing is not enough (which partly depends on your power)
That is why in end-game content like TOMM, IC, power boon is always better than crit severity boon. However, if you just pursue overall healing in ACT, or wanna max your blue shield to look cool (as OP healer) you should choose crit severity boon.
For dps:
In TOMM, with crit severity boon you will deal about 2%-3% more damage than with power boon most of the time. However, if you fail to crit, it has chance that you guys will fail to skip some mechanisms such as charges, or fail the last phase dps check.
If you choose crit severity boon it is the same as let rng decide your performance. People want more certainty sometimes so they can do better job in prediction and rotation management. So whether to choose crit severity or power boon in tomm really depends on your goal.
If you know you are in a situation where failing to crit in the last dps check will cause your whole run to fail, while with power boon even you guys fail to crit in the dps check you can still finish, then you should definitely choose power boon.
If you are doing a challenge run where only crit in the last dps check will guarantee success then you should choose crit severity. For example when people just begin to do tomm and there is only 10% chance that your group can finish, then choose crit severity boon (gamble here is beneficial for you); or if you are in a situation where tomm is too easy for you, choose crit severity boon, because you know you can still finish even without crit.
To summarize, normally you should use power boon, but in extremely hard or extremely easy runs, choose crit severity boon.
For tank:
Use crit severity boon if you can cap your crit chance at 50% (for more aggro).
(Same theory applies to pvp although it is a little different and more complicate. In general, you should choose crit severity boon if you have 90k+ crit. For defensive stats, defense>crit avoidance most of the time; but if you are super squishy or super tanky already, crit avoidance>defense)

Comments
I had already thought about it, but I prefer to follow the majority who follow the max stack thinking in Power. Even though I have a lower gain in the increase of damage, it is 100% effective whereas if I chose critical severity I would have an increase with a 50% chance, even if this was higher.
Due to the new damage formula, I believe that power is also the best choice for solo content.
There is a noticeable difference between adding 15% crit severity to a guy whose crit severity is below 100%, and lets say about 130%. Moreover, it is simply unreasonable to pursue critical severity if it is not backed by power. Pursue of critical severity can only be beneficial if it is your weakest point.
And one more thing: Pally healer. The blue shield is not just to look cool. As pally can have a guaranteed critical hit for raising a barrier, the critical severity versus power question has completely different background.
For a balanced character the difference Power/Crit severity is just a theoretical, meaningless question. One is just more random.
My point was that balance is in this case better than single-minded orientation, and that critical severity should be pursued only after the power is reasonably high. Here I completely lost you. So, it is important to exactly determine the difference in output up to the 3rd decimal, but when the critical severity's role is doubled, we will omit is as meaningless?
In that case, I guess this whole topic crumbled as meaningless.
