I'm B767Driver... I prefer to stay at a higher altitude, intercept the glideslope sooner, and get established on a final descent profile earlier. Less mucking around with power settings, and a stabilized approach leads to better aircraft control and landings, especially in the weather.
About false glideslope indications: Yes they are certainly possible. If I'm flying an approach and I'm lucky enough to have a copilot, I ask them to verify the altitude passing the FAF. Even before that, though, you *should* be able to recognize that you are descending at some crazy abnormal VVI (underlies the importance of understanding and calculating desired descent rate). If I am staying on glideslope, and my VVI is 1700 fpm, well, something isn't right.
Then again, to each their own technique!
