I commuted for months the same route, about 12 miles each way. Sometimes with my Bianchi, brakeless, in 23/25c with Schwalbe one front, Durano rear, mostly in my Arkose SSCX in 38c with Vittoria Hypers set up tubeless. The results were clear, the Bianchi was faster even tough I was spinning out as soon as the road pointed down.
I tried to put similar GI in the SSCX, pumping the hypers to an absurd 60psi, still was slower.
In the end I was using the Arkose everyday at 40psi. On road was fast enough to keep with fellow roadie commuters, way more comfortable and I could run very fast in gravel, canal paths and farm tracks too.
None of this very scientific, the Bianchi was lower and longer, but that's what I found.
I liked 38c but you notice the rotational weight. Not slower but feels slower.
