Just wanted to note that I quite like the admech-variant of the Providence; found one early one game and it makes for an excellent flagship; the asymmetric weapons configuration makes for an interesting sort of a forwards-or-right-broadside setup. Ended up using mostly regular ballistic weapons, with a tachyon lance on the left.
(Not quite as impressed with the Throne; it's not a bad ship, but not a great one either.)
Also, the Config-H Regalia is my new favorite type to give to the AI; like the Config-B, it's got enough dissipation to fully support its weapons, and like the Config-A, it's got a mobility-enhancing ship system that helps the AI survive when it overextends or gets flanked - and, thanks to the burst damage boost from its ship system, it does this without any significant sacrifices to overall firepower. (Though, okay, it may end up getting left behind other configurations late-game; I haven't had trouble with the things running out of CR time yet, but I can see that being a potential issue in larger fights.)
Speaking of, I really appreciate the reduction in Regalia maintenance penalty; it means I can actually keep one in my fleet without feeling like I need to haul around the high-maintenance Halbmond, too. (The Halbmond's still a must-have if you're fielding multiple Regalia, though.)
The new plasma cannons are fun, too, though somewhat situational; they perform a bit like HE weaponry does - not that great as an only gun, but providing a solid anti-armor punch if you've got other weapons to break through shields.
