I've had the flat plate ones short on me in an EICO audio signal generator (both the one in it and it's replacement that tested good before installation, but not after). Never tried the X ones, but I'd assume they were better than the flat plates since the later 6X4 and 6AC4 used and those and were considered more reliable than the 6X5.
