No, I've never had any flare ups or other problems with gasoline. I have had flare ups with white gas and an XGK, but only until I got the hang of it. Nothing serious. Just torso-sized fireballs.
I've also had no problems with the much-vaunted gasoline odors on the sleeping bag, etc. My MSR bottles have o-rings that are in good shape, and they simply don't leak. They're quite well made and reliable. Just in case, I carry them where a leak wouldn't be a major problem. But I've never had any problems, and probably never will.
And I absolutely love the new options for touring that the ultralight siphon system has opened up. Blows alcohol's availability right out of the water. It (relative availability) was closer before; now it isn't even close.
Much prefer the gas. Fine stuff. Many times less money. *Much* higher energy density. Hotter, more useful and beautiful flames. Way more adjustability. Way more versatility. Way more power. Way better for my applications.
Love meditating on the beautifully and brightly glowing metals, and the strong blue flames. Plenty of reserve capacity -- excellent back, excellent kick. Finely robust.
One of my last dalliances with alcohol stoves ended when I had the two girls side by side:
The alcohol stove looked so weak and anemic and lame. The multifuel stove just blew it away. Across the board.
Across the board.
That was about it for me.
