I've used the iPhone 8 and the iPhone X -- and the winner is clear

Apple now sells three premium iPhone models for the first time in the product’s history.

So, which should you buy? The iPhone 8? 8 Plus? X?

I’ve used all three models extensively. Here’s how they compare.

Both phones are powered by the same processor, so you won't notice a difference in speed or performance.

They both also run iOS 11, the latest version of Apple's iPhone operating system.

But that's where the similarities end. The iPhone X has a brand-new design with a larger screen.

The iPhone 8's basic design hasn't changed much since 2014.

The iPhone X has a sharper screen that uses OLED technology. It was recently rated the best smartphone display ever made.

The iPhone 8 has an LCD screen. It's still good, but not as good as the iPhone X screen, which can display deeper blacks by actually turning off specific pixels.

The iPhone X has Apple's TrueDepth front-facing camera system. It's used for facial recognition and enhanced AR features like Animoji and better Snapchat lenses.

The TrueDepth camera can also take portrait selfies.

The iPhone 8 just has a standard front-facing camera. It doesn't have Face ID and can't take portrait selfies.

The iPhone X doesn't have a home button. You swipe up from the bottom of the screen.

The iPhone 8 still has a home button with the Touch ID fingerprint sensor.

The iPhone X's rear cameras take great photos. Both lenses have optical image stabilisation, which means it takes better shots in low-light environments while minimising the 'shaky cam' effect.

The iPhone 8 only has one camera lens. The 8 Plus has two lenses, but doesn't have dual optical image stabilisation.

The iPhone X is expensive. It starts at $A1,579 for the 64 GB model. The 256 GB model costs $A1,829.

The iPhone 8 starts at $A1,079 (64 GB model). The iPhone 8 Plus starts at $1,229 (64 GB model).

If you ask me, I think the iPhone X is much better than the iPhone 8.

The iPhone X nails it across the board.

It has the perfect form factor, thanks to its large screen and minimized footprint. The iPhone 8 design feels stale and outdated as it enters its fourth year.

The iPhone X also represents exciting features that will become standard in smartphones over the next several years like facial recognition, super high-res displays, and advanced cameras.

The iPhone 8 is still a great phone, and you won't be disappointed if you buy one. But if you want the best of the best, the iPhone X is the clear winner.
