Low initial cost bikes I might give a minor edge to Priority because they pretty much stick with belt drives and are well known for it. Though the Head mainly has parts that are maybe a slight notch better on some fronts. In the end if I am looking for a good starter geared belt drive the Priority Eight would be my choice. More modern standard parts, 8 speed Alfine (vs Nexus on other stuff), carbon fork to loose a tiny bit of weight but add in some vibration dampening. It is a good solid modern bike which should last quite a while with good care and is right under 1k.
