SDS's on low speed are great and will drive almost anything in.

That applies to any mains drill that can go slow enough. Nothing to do
with it being SDS.

Many SDS drills have their gearing set such that their top speed is in the
900 - 1200 rpm range. That tends to be somewhat lower than ordinary single
speed drills, and closer to the low gear on a two speed gearbox drill.

I drove in 6" screws effortlessly with an SDS - with SDS turned "off". I
used grease on them so as not to snap off the heads.
