I definitely prefer fill ptobes to quick connect. There is no manufacturing standards for guick connect. It is a mismatched cluster jam. Some fit together, some don't. Contrast that with fill probes. Fill probes always work smoothly and efficiently. Fill probes will not fly off under pressure as the quick connect will if not fully engaged. The argument I hear for QC is universal fit, fine concept, failed execution. I'll take a probe over QC whenever possible
