At low levels, particularly min AP, the racial ability of battlewise wizard is not so significant as is based upon multipliers of low numbers. As such you are likely to gain a better stat advantage from the min arts of classic wiz. LAck of talent points etc means the benefit of the offence or luck talents is also reduced. As such it is probably correct that classic is more versatile for min AP MG. At full AP I would expect that battlewise is more competitive, but cannot comment on which is better. When I was level 5 wizard BW did not exist.
