The only difference I'm finding in these SSDs are long-term effects of write-wearing and performance. Samsung has consistently been good about keeping performance after having a ton of write cycles (http://www.anandtech.com/bench/SSD/730
I've also found ways to shorten reinstalling Windows, mostly by keeping a system image somewhere after I've gotten it to a "good state". Takes about 20 minutes to get up and running again. And usually Windows Updates are done in huge chunks anyway. I guess the only problem is some of the programs in that state are stale, but thank goodness for Ninite.
