a well designed wheel that happens to be forged will give you the strongest wheels, I have seen wheels costing 120$ surviving things that a 600$ wheel didn't , wether in impact or stress.... amongst the best out there: ( and be carefull not all the models from a manufacturer are good)
Forged:
BBS
Team Dynamics
Racing hart
Fikse
Forge Line
Volk
Mugen
SSR
Cast:
BBS (some models)
Team Dynamics ( some models)
Rota(most)
OZ/Prodrive (some model)
BSA (very surprising)
Racing Hart
Advan (some)
basically its not always easy to stick with one manufacturer and say ALL their product are the best.... you got to investigate a bit...
