The Symmar S was not quite as deadly sharp as the newer plastmats from the big four, but it had a somewhat smoother out-of-focus rendering and a tad less contrast, for when those kinds of characteristics might be desirable; and it can usually be had for bargain sums, since it was an abundant lens in its day. You could do a lot worse. I did almost everything with one of these for over a decade. If you want a more critically sharp lens in smaller size, the 210 G Claron is a stellar performer and also tends to be a bargain at the moment. If you need a small lens with a
bit higher contrast and very very sharp, I'd recommend the 200 Nikkor M.
