Nope, there is one key component that changes by manufacturer/OEM, and it is key to longevity - capacitors. Cheapo brands will have cheapo (ironically, one brand is teapo) capacitors, and as you move up the chain, often but not always of course, the caps get better. I buy business line just for that reason; it's usually beefier hardware.

Heatsinks can matter as well. One brand might ignore a hot PLL or volt reg in a dead spot, but another one will include a channel in the design to keep that chip, which can fail, within specs.
