I've not been to Japan, so did some searching for links that may help you decide.
Here's a blog post which provides an in-depth description of what they thought of the service, and it sounded pretty good.
There are video reviews of the bus service on Youtube.
Their first class seats look INCREDIBLE.
And from comments on The Thorn Tree and more, it sounds like the quality of seat depends on the bus (like the first class ones above), but nobody seems to have had a problem with reliability. And this is Japan after all, if you're not reliable, you aren't going to last long....

I totally advise against using their services. Check out the following website:

Simply put, unless your only concern is money and you are fine with unexpected traffic jams, inconvenient boarding locations (10 mins walk from any nearest train station) and being treated rudely simply because you are foreigners (they treat Japanese nicely) then take it.
