Which reference electrode to select for electrochemical measurements? The one with Vycor or ceramic frit?

Is there any significant difference in quality and accuracy between reference electrode with Vycor frit (porous glass attached with heat-shrink tube) and the one 
equipped with ceramic frit (molten in the glass tube) like in this example https://redox.me/collections/all/products/ag-agcl-reference-electrode-70mm
