Best eternal potion

[Jadeite]

Haste. Permanent haste is great, although depending on the campaign, boots of speed might be sufficient.
Good Hope. A permanent +2 on about every roll.
Righteous Vigor. 1d8 temporary hit points that stack with each other up to a maximum of 20. Only works with melee attacks, though.

Any other good choices?

Blood Rage from Orcs of Golarion might be another interesting choice. +10 morale bonus on strength, -5 on AC. Ends if the character falls unconscious. A character with a starting strength of 20 could get a strength score of 60 by 20th level (20 base +6 enhancement +6 size +8 alchemical +5 inherent +5 level increases +10 morale)

For a Vivisectionist a potion of Burst of Speed can be rather nice. +20 foot speed, move through spaces of larger creatures, and movement doesn't provoke AoO. Great for setting up flanking or reaching a flat-footed target before their init comes up.

How does Blood Rage work with the whole "ends if unconscious" thing? Seems like something better for Extended Potion rather than Eternal.

Depends what you're facing.. greater invis might be nice.
