Everest may be statistically less dangerous, but I suspect that's because the vast majority of climbers today (really, all except a handful of Sherpas at the start of the season) are climbing with fixed ropes on guided ascents. Everest today is still a dangerous mountain, but the dangers are themselves statistical (bad weather, illness, etc) more than technical.
I think the the fact that the dangers are mostly statistical is what makes Everest so dangerous. Not to make light of the difficulty in summiting Everest, but you can literally just hike to the top. This invites a lot of amateur climbers who lack the experience to even recognize dangerous situations, much less deal with them.
One of the guides in a documentary on it said that if Everest was at sea level, you would take your kids to summit it. But the altitude makes it a completely different animal. I wonder what the statistics are on frostbite and amputated body parts (fingers, toes). All of the documentaries I've watched seem to include a pretty high rate of some kind of frostbite in many of the climbers.
