Tradeoff between killing your battery or killing your SSD then I guess (if you have an SSD of course). And wasting time when booting, my experience with hibernation is that it isn't that much faster than a cold boot. Suspend is more or less instant.
If the full contents of a 16GB memory are written to disk for hibernation daily, with say another 50GB of work, that's over 6 years before you hit the lower limit. I probably wouldn't trust a hard disk that was used that heavily for that long either.
