Which Iphone is the best to get?

I was wondering which iphone is the best one to get, suiting me.
I don't want the Iphone 5 i'm only really looking at the differences and price range of the Iphone 4 and the Iphone 4s?

I know that one difference is Suri? Is it any good and what is the price difference from these two?
I would please like a list of details and comparisons? And personal experience would be appreciated.

AND what shop to get it from and which is the cheapest?

The iphone 4 & 4S is the same the only difference is that the 4S has Siri & the 4 doesn't. & if you wanna buy cheap cases for your iphone you can buy them on eBay, or amazon.

I have the 4S and love it tho I still find Siri a bit useless. I rarely use it. Apple basically threw the "S" on the "4" to charge more. My friend has the 4 and we've compared an really I would've been 100% ok with getting the 4 instead. I wouldn't get the 4S unless your really going to use Siri but honestly voice corollary basically does the same thing.

Of Course the iPhone 4S is the better choice, trust me the speaker is louder, video and photos are much cleaner.siri suck a google voice search app is much better for understanding what you said and facts but Siri can if you ask send texts, remind you of appointment, set timer, set alarm, read back new text and email, if you have a lot of texts or email it won't the4 and the 4s are separated by maybe 60, 70 bucks depending on what gb. IPhone 4 speaker is a joke but a 16gb is around 200 bucks but I would get the 32gb iPhone 4S

Iphone 5

No iphone.
Siri is annoying and stupid.
Apple overprices everything. IPhone 4s and 4 don't have anything different.
