Not best, only. st_usbfs_v1 is for ST's USB Full Speed peripheral implementation version 1. ST has a very similar, but different version in some other devices. They also have a completely different USB implementation they licensed from Mentor (the classic "dwc_otg" core) as found on all the devices that support USB-OTG: (including f107) Even this peripheral has versions and differences.
