If in doubt, follow the glideslope if the runway has an ILS.
KK,
Only if the the ILS/GS threshold crossing height is adequate for your type. If you are going to do this, also make certain you know what you are doing when the reverse applies, there is an abnormally high GS threshold crossing height ---- who remembers the old ILS on YSSY, it was 77 ft, a Lufthansa DC-10 that did an autoland skated right off the other end.
Know your facilities and your aeroplane.
