Personal view, but I'd treat electric impact wrenches with caution. So easy to cross-thread/over-tighten/strip thread etc. Hand wrench and torque wrench would be my recommendation.
No need for an impact wrench at all, especially changing wheels. I managed for years without a torque wrench either, but for the sake of £10 or £15 they're a worthwhile investment.
