tho i love HO, but i want to highlight some of S4 features wins over HO    so that ppl will think before buy.. anyhow, good consumer knows the product before buy

S4 goodies:
always wins over HO on benchmark tests.. so if we list down here, it already a few features such as CPU processing power, GPU power, net browsing speed etc. (i'm not good at this, but can read over the web) 
bigger screen
[what impact does it make to have another 3,000 Antutu score in today smartphones, I even feel TW is more lagger than Sense]
Amoled (goody or bad? personal preferences)
[I din mentioned SLCD3 is better than AMOLED]
expandable storage
[I have an OTG]
removable battery
[Only this area S4 wins but your lose a solid unibody construction]
longer battery life
camera pixel density (doesn't mean the S4 camera won in a whole only pixel ok.. hehe)

Every company has their own strategy in designs. Samsung had proved again to the critics that keeping their own design signature cues in their phones is still a right move. Personally I don't find Samsung designs "horrible" or any other manufacturer phone designs. In current stiff competitive market, I am sure Samsung and Apple know much better than all of us in deciding its design.  You can point out what you dont like about it.  If you dont like any of the phone manufacturer design, just don't buy it. Personally design is in my lower rank of criteria in buying any smartphone. No phone manufacturer these days comes out with ugly design - it is just a matter of whether one likes it or not. I have openly said here I had never like HTC One design on its front speakers ( though many of you will disagreed ) but I still buy the phone for its other purposes/value. I still prefer S4 design over it anytime and I own both phones

So if I have alrdy rooted, is it advisable to s-off?

Wrong.  With the HTC One, you don't need to S-Off to flash kernel from ROM through recovery.  Unlocked bootloader for the One can do that as well, no fastboot needed.  S-Off advantage for the One is only to get the LOCKED status back.

Wow I saw the quality and I must say it does not belong on the HTC One

One reason i choice htc one is 4G, butterfly s no 4G....

You need to tell us what is your criteria in choosing a phonw.
