IPhone 4 new or iPhone 4S used?

I'm debating if I should get a new iPhone 4 or used iPhone 4s.

An iphone 4 is way too slow compared to an iphone 4s.
But both devices will make you suffer, whenever apple stops firmware updates you won't be able to install or update any apps. And worse.
Trust me. Get an android phone. If you're looking into the older models, look into htc one.
Also, the iphone is for ignorant little bit#ches

IPhone 4S used in good condition.
