Someone inferred that "GPS is best". GPS is excellent, but if I'm trying to get home on a murky day, then my favourite is ILS every time. Belt and braces-like, I use GPS and VOR and ADF and anything else that's available (RIS or RCS is nice, too).
Which is "better"? The one that works right now - which has sometimes been the poor, maligned, clunky ADF, which nevertheless got me safely down where I wanted to go, without needing to divert somewhere else.
Flying a G-reg on an IMCR, I fly the ILS down to the IR minima - the "IMCR recommended minima" are an interesting checkpoint on the way down, but I certainly don't go around at 500 feet on an ILS.
Flying an N-reg, there's no problem because the IR now works.
