Hello! I am no where new to Android however I am new (maybe) to the Sprint network.
I am currently on Verizon using the HTC Rezound (damn good phone) and well because of company changes (dads work) are family finds in their best interest to switch over to Sprint.
I have done some research on both phones on the LTE network that Sprint is providing. Seems like the network is really holding back the true potential of these phones, even on LTE. I know that both phones have 4G LTE radios, 1.5 gHz S4 CPU Chips, 8 MP; 1080P HD camera senors and ship w/ ICS.
I love my HTC, the build quality is second to none, the Snapdragon (S3, I know the EVO has the S4) is a great ship! So I feel more bias to the HTC. The reveiws that I have seen said that it gets better Quadrant scores, better widgets, has a durable feel and has better personalizations for the end user. The kickstand is a nice touch as well as "ImageSense." HOWEVER, its does only have 1 GB compared to the GS3's 2 GB. And am very partial to the removable battery.
But on the same note the GS3 has a positive features as well. I love the fact it has a removable battery (just my personal opinion) it also has all the "Biult for Humans (which they are calling Samsung Motions)" and finally a 2100 mAh battery. The biggest down fall(s) I see with GS3 is the fact that has a plastic cheap feel, the sleep/wake button is on the side (hate that) and that you can't personalize it like Sense 4.0
But these are just my opinions, I'd love for everyone else to put in feed back.
