About the only good side to Bacchus is that it provides the greatest public order benefit at Pantheon level for the Julii, plus the Priest of Bacchus is a decent ancilliary.

Unfortunately the vices Bacchus temples tend to produce in governors do limit their uses: you could have a single city with a Temple to Bacchus governed by an otherwise useless leader, and everytime he gets a new Priest of Bacchus as a follower, have another leader visit and take the new priest.

Ceres isn't that much better, it does boost population growth but it then gives the weakest public order bonus of the Julii temples, so you run the risk of disorder due to squalor, etc.

Jupiter is really the only Julii temple without any flaws.

As for the Brutii and Mars, that can be handled with a similar method to the Julii and Bacchus, although the troop production benefits make them far more useful. Designate a city as a troop producer, assigning an otherwise useless governor - perhaps giving him a retinue with ancilliaries that benefit troop production - and then keep all your other leaders away! You get lots of boosted troops and most of your leaders aren't total fruitloops.

Juno and Mercury are both solid temples, with no flaws, which one you pick is a matter of preference. You perhaps don't want too many Mercury, needing to keep your income reasonable to avoid getting an excessive treasury which can gain your leaders various vices.

The Scipii have the best overall Roman temple selection in my opinion. Place Temples of Neptune where you want to build your fleets, with the side benefit of armour and weapon bonuses to troops as well. Temples of Vulcan become your equivilant to the Brutii's Mars, without messing up the governors at your main troop producing cities, and Temples of Saturn provide great generic temples, with the added benefit of armour and weapon bonuses when you hit Pantheon level.
