Tacsol as it is what I've got and shot the most. Stupid light.
I've owned a factory bull barrel. It was very accurate, but very heavy. Just ask @Kruejl
Not the cheapest thing though.
X-Ring™ 10/22® Barrel Upgrades
If you are packing I agree with the X-ring. Super Light, good looking barrel. I have put them on at least 15 guns for myself and others and everyone loves them.
