My absolute favorite ship-based weapon is the phaser lance used by the alternate Enterprise-D in "All Good Things". But that's not on the list, so I went with the Defiant's pulse phasers.
(My favorite *personal* phaser is the 29th-century one that was used in "Future's End". Mostly because, like the phaser lance I just described, it actually behaved like a light-based weapon should: there was no noticeable "time" that the beam travelled. With most phasers we actually get to see the beam move, which seems a bit odd, as any weapon based on light should not have any noticeable transition time. But that's a minor nitpick, really.)
