I am really debating on which one to buy(s3 or iphone 5). Since both competitors are pretty tough which one do you guys think leads the game. ?

 no competition at all. Go for S3

SIII No doubt!

 Buy it from costco wireless. Its 179 with free activation. Mine is enroute to me 

I'd go for note 2 coming mid-november to my carrier verizon(they released statement yesterday, they're bringing it. yayyy),
but if you want to choose from those two..
close your eyes and grab that s3...

If you are already into Apple ecosystem and you are fine with 4inch screen then go for iphone 5. However, if you are not into apple eco system and size matters then go for S3.  Its all about what you are looking for. If Map is something you are going to frequently use then Iphone maps sucks with compare to google maps. Specs are not everything but if you do care then take a look at this link.

 Galaxy s 3 of course , dont be isheep :D

why windows phone is not in consideration?
I personally dont like the building material, shape and feel of galaxy.

 shivanagar windows !!!  lol 
no comments :) 

 i am using the quadcore s3 and i am happy with it. i dont have an ip5 to compare.
i think the choice will depend on your usage type. one another non-tech factor is the resale value.

 hope this helps 

you should choose the phone that best fits your needs... if u know the stuffs u can make both phones work the way you want...

I have heard rumers iPhone 5 have holographic key board and holographic like watching movie thing nothing beats that I am using nexus Samsung amdrooid 3g for now as soon as my con tract finish after 2years I am buying iPhone 5 .

I completely agree with Rahasya. If you already hooked up with Apple-o-mania, i d suggest to stick with it. I personally use iphone 4s n happy with it. From ipad n iphone, using icloud n the whole bunch of applications (free) available with apple, i m noway to change my mind.
Having said that, i recently checked s3 from a fren of mine. I figured its kinda hard to conveninetly tap buttons @ farthest right top corner while holding phone on your palm. Iphone doesnt change the phone width, i guess they have worked on length couple of inches or may be more...
Choice is yours !!

 On that note, here is the drop test. Probably Iphone 5 is going to be like bmw with classic dashboard and s3 be like hundai with dhinchak dashboard.

 

 

Samsung S3 is the best.

Few things i like about iPhone
1. Signal reception. I don't know how is it on iPhone 5 but i have heard SGSiii does not have good signal reception compared to iPhone 4s. I used to have htc phone and they sucked reception wise, compared to iPhone 4s my wife was using with same service with att. So now the first thing i look for is reception quality before i buy any phone. I Was looking to buy SgSiii but didn't find good reviews about reception. Thats what stopped me to buy it.

2. Battery life: i can go for 7 hours screen on with heavy usage on my iphone. I found SGSiii lasts about 4 hrs with screen on.

These are the 2 things i look first before i buy any phone.

3. iMessage: this is very useful to me. I can send text messages free text to anyone and anywhere in this world. All my friends and families uses iPhone. So thats even more convenient for me. I even send texts to Nepal for free. I know there are other apps like viber but sometimes they are not relaible like iMessage in my opinion.

And the last one:
FaceTime: I don't even need to use skype.

These are the things i do on my phone 90 percent of time. And most of my friends and families uses iPhone so it's lot easier for me. It's just me. You might have different scenerio. I am just giving my 2 cents :)
