Which rear camera to buy?

I’ve had recommendations to buy a replacement rear camera for the 6s Plus from Mobile Sentrix, Injured Gadgets, and of course, iFixit. They are $7, $20, and $70, respectively.

Do these phones differ in any important ways? The suppliers all have good reputations and feedback.

Which to buy? And why?

Thanks.

iPhone 6s Plus Rear Camera

This camera from iFixit is $70. I can have the camera replaced, including the price of the new camera for much less than this (US $45-50) locally, here in USA.

iFixit, you need to qualify the value of your camera. Since Apple doesn’t sell phone parts, it can’t be OE. How does your aftermarket camera differ from any one I can buy online for half or less, or the one provided by the repair shop around the corner?

Not trolling, just wanting to repair my 6s-Plus and spend $$ for parts and not throw $$ away.

Thanks.
