Meh. People keep telling me that, but I have no problems on my tablets with Touchwhiz.
OH YOU HAVE PROBLEMS PAL YOU JUST DONT KNOW ABOUT THEM 
Nope, you have problems, and I refuse to buy into them. Even after others have tried to show/convince me. It works for me, so that's the rubric I always use 
this
if you have issues w touchwiz don't buy samsung phones?
I like the hardware and the camera tho
that ^
the only thing stopping you then is a root and a stock rom
using flagship bloatware roms make me nauseous
Stock roms almost always suck, and even when they are okay, carriers do their best to screw them up.
If you want to hack... Beware
Some phones have a locked carrier... (Samsung and LG do this)
ATT&T and Sprint play this game, and while you can unlock most after a year of continuous service (usually), Sprint is a real bastard about it, especially on prepaid. If you fulfill your contract but terminate service, they can try and force you to do another year of service before unlocking the carrier. They have also been known to implement black lists of phones they refused to allow to leave (before the rule change). Sprint blacklisted my S4 and then when that was lifted, tried playing the "needs to be online for year first" rule. At which point I told Sprint to go to hell after 14 years of service.
And the bad doesn't end there on Sprint Prepaid, not only do they do that, but Sprint has suppliers remove the menu system to allow you to port the phone off of Sprint. So if you have say a nice prepaid Galaxy S5, because it is capable of being ported out, Sprint has the supplier (Samsung) remove the menu, so their associates will tell you it can't be ported out. This was made legal by the new FCC rules on porting.... Which Sprint helped write. They left this loophole in it and Sprint was prepared for this well in advance, so even if it's an older phone, they already had that removed in expectation of it. Technically, if you add the file/menu back, it can be ported, but you still need an unlock code which they will not give you, claiming it's impossible, and while a third party can get it, is it REALLY worth it for a phone that will be limited to slow speeds on other carriers? Sell it and move on.
More insidious... Some phones have a locked bootloader. (Samsung loves doing this for AT&T and Verizon)
This means you can root and rom it, and port it, however, you can ONLY use a rom which uses the same kernel. So if it came with Touchwiz or any kernel modifications, you are stuck using a rom based on that kernel. No one has cracked the S4 Verizon bootloader despite a nice bounty to do so.
Not only do phones come this way, but the first AT&T S5 had an unlocked bootloader, then the second or third update they locked it.. Those older AT&T S5's fetch a nice premium since you cannot roll it back. In fact rolling back much of anything on a Samsung tends to make it a permanent paper weight. This is by design (KNOX).
If you want to buy an open phone
Your best bet is T-Mobile, who doesn't usually lock the carrier and almost never locks the bootloader to my knowledge. Their phones are almost 100% compatible with AT&T and the rest of the world (including 4g). T-mobile phones often fetch a slight premium because of this. Typically Sprint phones are worth the least (by a fair margin at times), then AT&T and Verizon which often have similar pricing, with T-mobile selling for the most, barring special colors and features.
Remember, ALWAYS read up on your phone before you flash anything because while some phones are hard to kill (LG), Samsung are ridiculously simple. Do the homework first and this stuff is actually pretty safe. It;s not doing the homework that will get you in trouble. Admittedly, it's not always easy or clear, but must be done to do it safely.
Can you tell I've done this a few times?
