I rode the A and the 2/3/4 lines usually. Try standing near the edge of the track. You'll get a whiff. It's not just that either, there's also a ton of litter and way more homeless people in the system than I've seen anywhere else. It's unhygienic to the point that it's a joke to New Yorkers not to get on a train car that's empty. Never seen that elsewhere. Of course the state of the subway is a reflection of the city as a whole rather than an isolated issue, and that's true everywhere in my experience.
