Apple started taking pre-orders for the much-anticipated iPhone X on Friday at 12 a.m. PDT, a month after the iPhone 8 and iPhone 8 Plus were released. Now that all smartphones are available, some customers might be debating which one out of the three new iPhones they should get.

All three devices were revealed in September at the Steve Jobs Theater Tuesday in Cupertino, Calif. The iPhone X is now available for pre-order in 55 countries and territories, while the iPhone 8 is available in stores and online. However, the iPhone 8 hasn’t been as popular among consumers. Prior to the iPhone X’s pre-order date, KeyBanc Capital Markets analyst John Vinh said in a client note obtained by Reuters that people were waiting to buy the iPhone X or to compare the device with other models before purchasing the iPhone 8.
