Both my 3/8-drive & 1/2-drive are Snap-On, QT-series if I remember correctly. My 1/4-drive is a Snap-On electronic.
I used a borrowed Craftsman 3/8-drive years ago, once. I found out just in time that it was waaayyy off. The downfall of the electronic is the batteries, you just have to make sure you always have extras on hand.
To cover the range you are wanting you will need (2) different wrenches. The 3/8-drive will cover 20-100 or so, and the 1/2-drive will cover 50-250. I was also tought to never use (trust) the bottom 10% or top 10% margins of the wrench.
