So after a few games with Earthrise Hotel in place of Wyldside in my Noise deck, I can say that the main problem with this card isn't the initial cost, it is that it leaves you after three turns. If you play Noise like I do (and it may be fair to argue you shouldn't), you have now gotten used to letting Wyldside burn away for the majority of the game. Without being able to tutor for anything besides viruses, Noise depends on massive card draw, especially if you run standard breaker suites. (And let's be honest if you're only running Crypsis/Darwin while relying on Hades Shard you are a terrible person.) Even when I had Earthrise in my starting hand, I still felt "under-drawn" by mid game. Resorting back to one click/one draw after the hotel kicked me out really ruined my game's pace.
I personally feel that Wyldside + Daily Casts is a much better team than Earthrise Hotel + Armitage Codebusting. The number of clicks spent in each combo tend to average out, but with the former I get through my deck more efficiently.
I could see using Earthrise more in a Noise (or any other Runner) deck that doesn't use Aesop's Pawnshop. With Aesop's in play you always have an out if you get sick of wasting credits to WS. But if you would like to ditch Aesop's for a more traditional economy for some reason, Earthrise Hotel has the benefit of not having to marry it for the entire game.
For me though, Wyldside still suits my needs better.
