Probably neither. There are better options
The Enduro rim is narrow and heavy. Superstar… Well, it’s superstar.
Ex471 on either Hope or DT 350, or Easton arc27 or arc30, or the brand new Stans Flow or Arch rim – both are superb.
If you ride trail, then the arch is excellent, if you ride DH or DH trails then the 2016 Flow rim is hard to beat.
The DT350 is a great hub, but has a low pickup out of the box, which doesn’t *really* matter, the Hope pro4 and pro2 evo 44t have a good pickup, but are very slightly more draggy seals.
Personally, I think it comes down to… How loud to you like your hub? Noisy? Get it Hope. Less noisy? Get the DT. If it was between the Hope and dt240, it’d be the DT obviously.
Get yourself a good wheel builder, like moonglu, and get a decent rim on either hub.
