This a complicated question, yes i do have brand loyalties but they not unending.
CPU & GPU: AMD till i die (ex nvidia fan boy)
Motherboards: Asus/Gigabyte nothing else
Ram: Corsair Dominator Range but these days he G.Skill Trident is Peaking my interest
Monitors: What ever i like currently Samsung
HDD: Mechanical: Seagate SSD: Samsung
Keyboard Mouse: Razer/Corsair/Logitech
Watercooling: AIO Corsair/ DIY: EKWB/Corsair
Phone: Currently own iphone (hate it) but i loved Microsoft and Love Nokia. Hate Andriod.
Printer: Cannon (Home Use) HP Business
TV: Samsung (though there software not great)

So this is something that came from my dad. He always chose the Sony product over the rest. TV, Surround Sound, MP3 Devices and so on. And I see today I am the same, I always look at the Sony device first and then usually take the Sony brand over the rest.
