What I found to be the best option for survivability against the puppeteer is surprisingly an exotic everyone forgets, and it's riskrunner. Now before anyone goes and lops my head off, bear with me alright. Riskrunner grants huge arc resistances, boss uses arc (queensbreaker with a switch tbh) and the lightning strikes themselves are arc. While you won't survive a direct impact strike, you can survive a good 2-3 extra ticks and it takes about 4-5 shots from the boss. While arc conductor is active your chaining lightning to multiple targets, builds up light energy like crazy. Again, not saying it's a God of choices but it is surprisingly good for most encounters.
