AoS Mathammer

Now that we have several very difference weapon options for the mounted Lord Celestant I wonder if anyone has run the numbers yet? I'm not a master of Mathammer but it looks to me like the Tempestos Hammer still has the greatest damage potential, but is somewhat random. I really want to like the Stormstrike glaive with it's pretty major charge bonuses (especially against heavily armored targets), but I'm not sure about that mediocre 4+ to wound... Anyone have some thoughts/numbers on the different weapons options?
