Vigor will allow you to cap your energy less often and start with more energy after 'breaks' (boss lore whining, fight interupts like prof etc)
The problem is that on half the boss fights it is not that useful, or atleast not useful enough (e.g. Fleet Footed will give you the same DPS increase on Sindy because you can start each phase faster rather than start with more energy). Glyph of Tricks vs Vigor is a bit harder. Mostly depends on the target and frequency of your TotT usage I guess.
