Mostly they still just serve to augment or de-buff Shadows.
The problem is still their varying conversion rate - they might be able to pull off a godly insta-convert at night or in the dark, but most games are played during the day, which means their tags come in at under 1/5. Worse, they were given a fucking Throb rate, so you can't pull off all 5 tags by keeping the beam on them.
Snipers are still better all-round, even if their standard Tag is the same at 1/5 - they have no Throb rate, and good ones can pull off multi-shots to do a distance Tag at the same rate as Runners can perform a standard tag.
If you're into night games, have a lot of Shadows on your side (or there's a bunch on the other side), or can guarantee dark terrain, then you're good, but otherwise, stick with standard Snipers.
