I read about Makita, Bosch and dewalt perform better. there was a comparation done by Caranddriver ( I guess you already read it http://www.caranddriver.com/features...tested-gearbox). So I'll pick makita or hitachi due battery, however makita has better reputation. if we talk about track use, battery is what matters and size.

Makita should win over battery and size,
Bosch should be the best due torque and size

talking about value..
Maybe pick Milwaukee or hitachi..but again Milwaukee has better reputation as tool manufacture.
