Haha, well first off they're all Intellect / Discipline, which I think is still the best distribution for Titans, even with the Sunbreakers. If I need my melee, I can always run Monte Carlo -- plus the Stoke the Forge perk on the Sunbreaker can instantly refresh anyway on a kill.
Next, I wanted to prioritize Solar perks because of the new and shiny Sunbreaker, so my chest will increase Solar armor and my boots will grant the Agility bonuses after Solar double kills (which work for weapons too).
Next, both my boots and my chest have increased Sniper ammo, which I think is probably the best ammo perk to have right now.
And then lastly my gauntlets increase Scout reload and grenade throwing distance. Scouts and Pulse Rifles seem to be the go-to primaries right now so that reload perk is helpful. Super Good Advice, Zavala is selling the same gauntlets but with Pulse Rifle reloader if I remember correctly, so I'm tempted to pick those up too with Red Death/Bad Juju being so good.
