First off, unsurprisingly a Titan main. I think running is by far the most viable tactic you listed against a Sunbreaker. The thing about running in a 6v6 gametype is that if you take off running across the map you will probably run into at least one enemy more than likely resulting in your death. Sniping would work on a long range map but unfortunately not many exist. I think the SB to BD analogy is somewhat viable other than with BD, you could shoot at the super before they get close. SB doesn't have to get close. Another thing is the duration. Despite you not believing they nerfed BD, I have noticed a HUGE difference. First is the lunge range. I get short striked all the time now basically making me a sitting duck for shotguns. Second is the duration. I had time to kill one person at Blue special on Pantheon and then run straight back and kill one on Blue Stage and I was out. Meanwhile the duration of SB is much longer giving it much more kill potential. Despite all of this, I literally want one change to Sunbreaker. I want the damage reduction to be on par with all other roaming supers at 50%. If they can tank my sniper headshot because they are armor stacked and have solar armor then that is ok. But to attempt at a more balanced PVP with a class that has more reduction than others for no reason is stupid.
