After a myriad Android crappy devices (first being a Coby tablet, then many budget phones from Net10) the first device that grabbed me was a Samsung Galaxy SIII. I was coming over from Apple after iOS 7 offended me (I HATE flat UI) and Samsung was the only option out of the three (HTC One M8, with flat UI Blinkfeed, and a Moto with stock Android) that had not only a skeuomorphic interface, but it combined one of my loves--nature with it. It also offered many functions that reminded me of iOS--a Siri style assistant called S-Voice, to name one. Combining nature with skeuo really grabbed me and it was unique at the time. I still use the same brand today (tried others but they don't really work for me--I spend tons of time trying to emulate TouchWiz/OneUI and it's never a complete deal) and still make efforts to TouchWiz-ify them all, including sideloading all the classic notification and ringtone sounds.
Samsung is also the only one making unique enough (for me to consider it an upgrade) devices such as my new Z Flip 4. I also prefer their apps over Moto's, Google's or another OEM's (including LG's) because they offer features no others have, such as theming the messaging client with wallpaper and custom message bubble styles, or custom email sync settings, or a theme store that does custom-ROM-level theming of the system UI.
I hate that Samsung has removed the headphone jack and SD card, but at the same time all the flagships are doing it. I tried many a budget version but they were never able to keep up with what I do, which isn't much, but when your A-series or Moto E can't maintain a stable bluetooth connection, or make an NFC payment, well, that's not good enough. Also I like wireless charging after many issues with USB-C, another change I'm not too fond of.
So I'm still team Samsung unless they do something really bad like take all of that away. Even to this day I can still recreate TouchWiz Nature UX on their modern flagships in ways I cannot do simply with a third party launcher or icon pack, which is always skin deep. Just with Samsung's theme store alone I can recreate the Galaxy SIII's UI pretty darned close. The only missing bit is the touch sound, but that's all.
