Golem are better than all his secondary options, but then the Kyogre, then the Bite.
For point of comparison, my mon (2 SD, 4 Golem) are all 33ish (3, 5, and then 4x15 Atk) and just barely duo-capable under neutral conditions with a decent phone connection. With either partly cloudy or even good friends, it's much more comfortable.
Remember break points change with weather and friendship!
