Hum... the best thing is not a single weapon, but to have a good combination of them. For example: in Nemesis 2, 2 Options + Extended Laser + Napalm Missile + Uplaser. Superb!
By the way, could someone patch Nemesis 2 for having four options?
WORST weapon ever has to be down-double from nemesis 3.... first you had the already crappy up-double in nemesis 1 and 2 ... luckily it was replaced by ripple laser in salamander. but they threw it back in in nemesis 3, even with down-double! which meant losing your missiles if you activate it. so you could go from having screwlaser+photonmissiles+uplaser to having down-double only... how sad is that!
comes in handy in the bonus stages.. thaz all I can think off (okay, there's the downlaser thingy, but you have to EARN that one first.. so euh)
but I agree, can be a pain in the bud when *by mistake* choosing any double fire!
