This variation in describing different types of 'hammer' drills has cropped up before.
In some adverts (UK) the Bosch is described as an "impact" drill, and the Makita as an "impact/hammer" drill; I would prefer that they were called 'percussion ' drills; with the other type being described as "sds rotary impact" drills.
Part of my problem with wording is, that I tend to think of "impact drivers" as being for, err, 'impact' driving screws/lag bolts etc...
Think that both types, ideally, need to be available - depending on what's being drilled into of course. I find that SDS drills can be almost too fierce for softer brick for eg; but for sure, essential for drilling into reinforced concrete. Fwiw, I like the Makita Nemesis drill bits - they've served me well.
