i am not sure who wins here.. i know weather wizard uses his powers with less inhibition then storm.. like tornadoes inside ppl..etc..etc..
i know his power werent always innate and depended on his wand that was until a female writer screwed it up b/c she wasnt familiar with weather wizard..
storm subconsciously produces counter forces to cancel out effects on her person caused by the weather.. like counter winds, heat, cold etc etc...
i know storm can be pretty vicious when it comes to using her powers as well when the need arises.. like drawing out ppl's breath via vacuum, EMP to the brain disrupting the neural electrical impulses etc etc,,
i think in any prolong engagement of weather control weather wizard will lose even if it is the version with the innate abilities.. but, i guess i could see weather wizard use a brutal type attack and try to kill her with using a tornato inside her "if" she isnt immune or doesnt subconsciously counter the attack by turning it off or having an equal opposite effect..
over all i prefer storm over weather wizard,, i think she has better control feats and longer history then weather wizard.
storm 7/10
