I quite dislike Tokyo Station. It's huge and confusing for people who are on their first trip to Japan. At time of writing, there is a lot of construction going on, which makes getting around even more of a hassle.
Tokyo Station is also a notorious spot for bored Policemen stopping foreigners to check their IDs/Passports (Along with their pockets) Which is very surprising (the first time it happens and leaves a bad taste in your mouth).
Avoid when possible. Could be worse, but could be waaaaaay better.
The terminus representing Japan, Tokyo Station is tops in the nation for scale and beauty.
