Just got some feedback from a HTC one s user and they seem to be pretty happy with their purchase.

The One S is a fine phone, but overall you get less for your $$ at 4" and under in the Android world.
Example :
T-Mobile. First indicator here is that screen size isn't even selectable as a search criteria.
Next, What do I get for $99 or less vs the iPhone 4S 16GB?
First thing is LG MyTouch Q. 3.5" screen, 320x480 pixel, 2GB of memory and a 1Ghz single core processor. More a competitor to the iPhone 4 than the 4S, and even at that the iPhone 4 will rip this puppy to pieces.
Next, the MyTouch. Same hardware specs but with a much improved screen resolution. Still 2GB of memory. Still 2.3 Gingerbread.... It's free though. This one might be a worthy competitor to the iPhone 4, if it were not for the paltry storage and Gingerbread OS.
So at the $49.99 point, I see another 'MyTouch'. Better, 1.4Ghz Snapdragon single core with 4GB of storage and a 4" display. Still Gingerbread though. OK, this one can compete with an iPhone 4 8GB, but carries a $50 price premium vs the iPhone 4. It's not a competitor to the 4S - the display, OS (gingerbread), storage, and camera all make it clearly inferior.
So the first $99 phone I see here is the Galaxy S Blaze 4G. Now we're talking, a Galaxy phone!!!
With a dual core 1.5Ghz snapdragon (win), 5 MP camera (lose), 720p camcorder (lose), and Gingerbread 2.3 (big lose). It has 4G (win), Adreno 200 GPU (lose), and a 480x800 235 ppi display (big lose). 1GB of internal storage, with up to 32GB via mini SD card (extra $$). This phone gives you a lot less for your $$ than the 4S.
Next up is the One S at $150. This is the only phone I know of that can sorta match up against an iPhone 4S / 5. It's also over the 4" requirement, has a lower resolution display, lower PPI, slower GPU, and an inferior camera to the 4S. In its favor is a faster CPU, 4G, and ICS.
Edit: Found the Droid Incredible at Verizon for $99. This one matches up nicely against the 4S if we consider the 4S to compete against a 4" screen phone. Seems that HTC is the only company with serious competitors around the 4" screen size point. It's no 5, but it's also $100 cheaper. I didn't see anything at Sprint worth mentioning in this space.
But really, the point is -
Nothing I found, at least at T-Mobile, in the 4" and under space can touch the last gen 4S and in most cases the 2 generation old 4.
Bluntly...
I don't think the other phone makers are capable of making a phone good enough to compete with the iPhone 4S / 4 or 5 in a small screen form factor. It's pretty clear that they are not even getting close with current phones.
