Best Impact bits are hands down no competition: wera
Second contender i would say is: dewalt
For Drill bits: IMO the Dewalt titanium

DCD 985 make same power on small 1.5 ah as 3.0ah?

Most of what is said in that thread is accurate.
But to go into detail. Almost all power tool battery packs have a discharge rate. In the nicad days this was measured using "c".
In some tools, the tools that have a high power - draw rate, like a circular saw you should see the tool producing more power especially under load using the "bigger" battery packs like 3AH or 4AH. because most of these battery packs (NOT ALL) are 2 slim packs slapped together in parallel. These battery packs made of 2 parallel packs together, essentially doubles the discharge rate the batter pack is capable of. Also some battery packs are actually using the same number of cells, but just larger cells in the larger packs. The larger battery cells in most cases have a higher discharge rate. Most tools under load will draw more power from the pack. If the pack is able to deliver the power required by the tool, it essentially allows the tool to produce more power, assuming the tool was power starved, which in many cases it is.
also, this is not true for all tools, because some tools and battery packs have circuity that will limit the max draw from the battery and power into the tool.
