I agree. The amount of attention required by a quality sealed chain is a small fraction of what it was with the standard (i.e. unsealed) chains in 'ye olden days. Those old chains had to stay continuously soaked in thick, heavy lubricants, which was both time consuming and messy. Since the lube didn't generally stay in the rollers (unless you lubed every 100 miles or so), chain adjustment and replacement intervals were a lot shorter.
Most of the time when I hear someone complaining about chain final drives it's either people who haven't used a modern sealed chain, or (surprisingly) those that do have a sealed chain, but continue to maintain them like the old standard chains.
