TBN has the same eHP effect as RI and Sheltron. Each one has their advantages. Sheltron can be saved up and used back to back. RI and HoL are free to use with impunity.

TBN feels stylistically good to use because it negates part of the damage, but that's a subjective effect. The main benefit that it brings to the table relative to the others is in shielding your co-tank from a tankbuster, but it can't be used the way any of the other ones can on non-tankbuster level damage. You have to be more selective on what you mitigate. You also have to plan in advance what your cooldown strategy is going to be so that you can be at the correct MP level for those tankbusters.

It definitely makes the job more interesting, though. It's the only way in which you can effectively go 'above' max MP to store up an extra Edge/Flood for burst.
