Kyogre
During the first round with Kyogre, my best catch was a 93% with 15 Attack. When Kyogre raids ended, I powered him up to level 30. Today, I caught the elusive 2328. Both are WF/HP. I will be powering up the 100% (I currentlyhave 106 candies, plus another 250 RC on hand). The question is, do I keep them both as WF/HP, or is there a benefit to changing one of them to either Blizzard or Thunder? I realize that HP is the best attack, but are there any niches that would be filled with a different charged attack for this guy? I have a good supply (50+ each) of FTM's and CTM's.
Other top tier water attackers include 100% and 96% WF/HP Garys at level 35.

First of all, congrats and I'm pretty jealous. Secondly, WF/HP is pretty much the way to go. Had they kept Dragon Tail in its movepool a DT/BZ Kyogre would make a formidable dragon-slayer, but without it it's pretty disappointing. Thunder isn't a great move to begin with, you'd be better off using actual electric types in its place.
No problem in having multiple WF/HP Kyogres though. Come Regirock you'll want as much DPS as possible.
If you get a strong (means rain buffed) Kyogre and it has Thunder, keep it around for a while, because it makes a good Tank against Blizzard Kyogre or HP Kyogre as a raid boss. But I wouldn't use a TM to take one to Thunder unless I has something like 20 CTMs. And once Groudon (not sure, but fingers crossed) comes back after Kyogre goes away, you'll want all the Hydro Pump Kyogres you can get.
