I had been a 35 shooter for a decade and Q2 open up the 28mm world for me, and at f1.4 it's way more useful than Q2, and I will not shoot anything slower if it's a 28mm. It's also pretty easy to shoot from the hip with zone focus (even wide open). Never quite had the success with 35cron.
By the way the Thypoch 35mm isn't as interesting as the 28mm in terms of rendering, hard to put down in words, less interesting if you will.
