Subject: That's a tricky one.

It seems from the Battlestar wiki that Colonial ships use physical weapons exclusively, which means all that frequency-matching going on in Star Trek is entirely pointless. Memory Alpha claims that a Constitution-class could take 90 simultaneous photon torpedoes to its shields. How many high-explosive bullets is that? Should we assume equivalence to Galactica's high-energy shells? Colonial weapons are optimised for use against superconducting armour, and are designed to cause physical damage, which makes me think they won't be too effecting against deflector shields.
So how about going the other way? A phaser strike on a Battlestar's hull should be dissipated by that armour, since phasers are energy weapons. Destroying a Battlestar with phasers will involve heating the entire hull until... well, probably until you cook the crew. That's going to take a while.
Torpedoes? Uh... Memory Alpha thinks that a single photon torpedo detonation could destroy an unshielded Galaxy-class. And that's a physical matter/antimatter detonation. Star Trek ships don't appear to be armoured, so that's not a terribly impressive achievement... but it still speaks to the power of the weapon.
How well can a Galaxy aim? If it can hit a Viper accurately with a phaser, the Viper is probably dead (due to hull heating if nothing else) - but that's true of any fighter up against main guns. Energy weapons probably make hitting your target easier, though. On the flip side, phasers are probably useless against a Battlestar - but photon torpedoes are orders of magnitude more powerful than anything the Twelve Colonies have. Unless Federation shields are highly ineffective against Colonial weapons (Memory Alpha doesn't really talk about how well they work against physical objects), I think the Galaxy takes this one.
(A Galaxy is somewhat under half the length of the Galactica, for the record. If the record cares. Which I'm not sure why it would. ^^)

PS: Best weapon to use is ultra long-range AI-driven drones consisting of an engine, a warhead, and a computer (for instance, take any fighter, replace the pilot with an AI, and replace the life support, weapons, and everything else unnecessary with bombs). Stick a few hundred of them out there on long-range ballistic courses, ramp them up to a few thousand times the acceleration human-crewed ships can handle, and watch your enemy burn from across the solar system. ^^ Doesn't make for gripping TV, though. ~hS
