I think they aren't dramatically better, but they do seem to sound better to me. Crisper, basically if you're happy with the sound that EarPods provide, you'll definitely be happy with the sound the AirPods provide.
They don't feel cheap, but I don't think EarPods feel cheap so they are pretty similar in feel. They do appear nicer looking than EarPods though to me.
For asking Siri to do one off tasks like 'shuffle all music' or 'play my recently added playlist' it's good, but for me I find adjusting volume or changing tracks with Siri to be tedious. To change volume I just feel for the volume buttons on the phone through my jeans, or I use my Apple Watch.
Overall I'm pretty happy with the purchase, definitely no regrets. It does suck up it's fair share of iPhone battery but I did use it non stop for five hours as I went about my day. I should also mention that when using it I also had my Pokémon Go plus connected for probably three hours or more and also my Apple Watch constantly connected. So for the most part, I had three Bluetooth devices connected at once.
It's as easy to pair as people say, and the charging case I keep in that small pocket that most pairs of jeans have within the front right pocket.
Also what I plan on doing is buying an iPhone dock, and sticking the charging case on that at night. Seems like a convenient way to charge it seeing as the lightning port is on the bottom. I tried this at the Apple Store on one of their demo docks, seems like a good place to keep it when at home.
I also did try watching videos on it, everything was in sync so there's no delay. On the negative side though, and to be honest it's not a big deal, but it did lose connection maybe three times for a split second, though the connection may have been interrupted. It was only those few times, so it wasn't enough to be an issue for me.
Overall, I definitely recommend these for anyone who hasn't got Bluetooth headphones yet, definitely a good way to go if you're looking at that route.
