It's like ridiculing someone who moved to the South because they were fed up with snow shoveling, and you enjoy it. There is no right or wrong when it's someone's opinion and we all need to respect that.
+1 to what George said! Everybody is entitled to their opinion and there are no right or wrong opinions. Opinions are based on personal experience and personal preference. They are not entirely objective and data-driven.
I also agree with him about chain maintenance: It may not be a big issue, but it's sure more complicated that the final drive maintenance I've expended over about 1/4 million miles on my four shaft-drive bikes.
