I have been using them for assassination missions on DBS small hard points, as it allows those to punch above their weight. They're quite useless against small agile targets because their long chargin times after you hit the trigger. A pre-charge module would be very handy. Also they run out of ammo pretty quickly, so they're only really useful if you're in an area of space with lots of inhabited systems where you can reload. If it would be possible to install a pre-charger and/or upgrade them with bigger ammo clips I would love them, now they're very situational. The low ammo count makes them unsuitable for bounty/voucher farming in RES/CZ's unfortunately.
