DeWalt DCD796 vs AEG BSB 18CBL: Comparing 18V Drill Drivers with 5Ah and 4Ah Batteries

Hello all,
I am facing the purchase of a powerful, universal, compact 18V drill driver - for years
I read, watched and the decision fell on DeWalt DCD796 with two 5Ah batteries. Today I had the opportunity to take a look at the AEG BSB 18CBL, on paper its parameters are even better, but ... well, I don't know.
On a ... gro, the AEG in the set, two 4Ah batteries and the BEX18-125 orbital sander, costs roughly as much as the DCD796. I didn't think about the grinder, but the donated one ...
Will you help?

I would have bought a DeWalt without hesitation, but not necessarily with 5 Ah batteries. With today's technology, 1.5 Ah is enough for basic work, large batteries are heavy and if such a battery fails, the cost is more when buying. I use a DeWalt screwdriver and I have a large and small battery to choose from, I prefer to do on the small one.

Thanks.
DeWalt bought, actually these smaller batteries do it. With a screwdriver equipped with larger readers, heavier batteries, working above the head can be a bit tedious. In general, the handheld screwdriver gives the impression of a concrete, solid and powerful device. For its size, it can do a lot. The head stroke does not break off but it is not concrete forging equipment. greetings

Substantive comparison of devices in the class of compact screwdrivers:
