DT240S is IMO best allround hub- King are “nicer” but DT are cheaper, quite a bit lighter, less troublesome in use… so who gives up all of that for nice?
But 240s are stupidly expensive new, I wouldn’t pay that- so the 350 makes a lot of sense. Or, do what I do- they’re a fantastic used option because they’re so reliable and durable, so buying an unfashionable wheelset and scrapping it for hubs can make a lot of sense.
(you do have to be careful doing this- because they’re so longlived, there’s still pre-15mm hubs doing the rounds and they’re pretty impractical to convert to 15mm.)
