Thanks for all the replies! As I am not terribly demanding on drum sounds at the moment (well, apart from the brushes) I have been sticking to free drum plugins (some of which are quite good in my opinion, and it helps not to be overwhelmed by choice).
I saw a discount of Vienna Jazz Drums (it's €57 at the moment), along with a favourable review somewhere, and I decided to try that out. It comes with a VST plugin, but no other software is required.
I am far from a reliable judge of sounds, but I am happy with what it provides: for the snare drum there are hits and swishes, and the other parts of the kit (hi-hat, ride cymbal, toms, ...) are available with brushes too. The sounds come across as nicely warm and authentic to me, and I like the velocity response.
