Depends what the recipient already has. For general DIY work I would
say that a hammer drill is more useful. I am a late comer to
cordless drills which I have bought in special offers. I have found
them convenient. My main concern is battery life when they are not
used very much.

That depends on what your walls are made of.

I have to use an SDS+, so a non-hammer cordless would be fine for other
jobs.

I'd agree with that. IMHO walls seem to come in two types only. Soft
enough to be drilled with a non SDS - in which case a decent bit in a non
hammer drill will work ok. And those so hard only an SDS will work.

Really? I think there are three sorts.

Lighweight blocks, which are fine with a cordless non-hammer. Don't even
need carbide bits, HSS will work.

Ordinary brick and blocks, needs a hammer drill. May be slow with a
cordless, for larger bits. I still often use a corded here.

Engineering bricks, traditional Breeze Block from 1960's, many types of
stone. SDS is your friend.

I have found that the Bosch multi material bits will drill hard masonry
things in the 18V combi cordless that I had previously dismissed as
un-drillable without the SDS.
