Arc1100 or RSL75 for flat and TT

[Kingston]

I am riding a set of DT Swiss Arc1100 62 wheels on my bikes (Venge and Shiv TT), but concidering a deeper set of wheels, like 80mm -ish. I intend to use it as a complete set on both bikes, the front with disc on TT bike.

I really like the DT Swiss, and it would makes sense to go for the 80mm Arc.
But, the new Trek RSL 75 got my attention.

On paper there is differences between these wheelset.
Arc: 20mm internal width, 180 hub
Rsl: 23mm internal width, 240 hub.

Any thoughts?
