As a low-time (just shy of 250 total hours) private pilot, I much prefer all-analog, as I personally find it much easier to take in information in a quick scan. PP and IFR instruction was both done with "glass cockpit" aircraft, and while Garmin's avionics are quite nice -- and were one of the reasons I took instruction where I did, I found that I like the all-analog setups better.

This has a side benefit as well -- the "glass cockpit" planes are much more in demand at the local flying clubs, while I can almost always get an older 172 or 182 with zero advanced notice, and they're cheaper too.

I won't opine about reliability or anything else; I don't have enough experience. I just know which I find easier to process.
