Why are people hanging on to 3.9/3.95?

My comp causes SM5 to crash before it even starts up. So the most recent I use was scc, and even then it was a pain to get the configuration settings done properly. Personally, sm5 is rubbish (I mean come oj, wouldn't you say that if it crashes before even starting up?) I stick to 3.9 because it is the most stable version of SM that I have played throughout the 6 years that I have been playing SM. I understand that the devs are improving sm each and every time, but for stability's sake, 3.9 all the way...
