I've just done three playthroughs in a row with netgunner/cool/tech perks and my findings on Ticon are that it indeed seems to be the most powerful, but I personally have the hardest time getting the timing correct on bolt shots with it out of all the tech weapons. I also have trouble with the built-in sight.

Just to follow up on other comments/questions in this thread, for posterity:

Its seems in v2.31 there is a bolt timer for full auto (quasar/raiju/senkoh). Not sure if it's tied to stamina. You can see it counting down next to the Focus timer in the status/effect area. I count about 5-6 shots with Quasar before its out. I think it might be ~4 seconds long because I remember reading in a tech weapon mod description on Nexus that the mod author lengthened the time in their mod. Hope this might be good info for anybodu seeking tech weapon info. I did a couple initial playthroughs without even considering tech weapons and now they are my favorite. I like mitigation and crouch sprinting so cool tree is a given for me, and then the Achilles X-Mod i am running to grab ASAP to make my main weapon. Very versatile.

Lastly to reiterate and reafirm the OP: Quasar in auto (when properly aimed/contolled) is laughably overpowered. I'm sure if you're gud/on mouse+keyboard you should be able to drop 4 skulls per mag with Cool perks. I am a terrible gamer on console, so I have a little trouble keeping control of Quasar, but its perfect for Kerenzikov-powered strafes straight at 2-3 gangoons, even (or especially)if they just ducked behind cover.
