Can't say I'm a fan of most of the glowing weapons (I'm fine with the ones that have a subtle glow) but then I also can't say I can think of a time when another player's glowing weapon has been a distraction or other bother to me. If it's my own weapon, I just glamour something else over it. If they make a player happy, let them have their glow.

The glowing Eureka armor is more obnoxious than any weapon I can think of.

The glowing special effects of combat actions are the worst since you can end up with layers upon layers of them happening at the same time unless you turn battle effects off completely. .
