How are Blackberry phones more secure than other Android OS devices?

Blackberry sells its phones as the clear choice for best security. How is the same Android OS that is used by Blackberry more secure than, for example, a Nexus device that receives monthly security updates? I can see how BB could have been more secure in the past when it still used its proprietary OS, but how is that still true?
BlackBerry does claim that their devices are more secure then alternative Androids. You are correct that the base OS is Android, but it's open source which allows different carriers and manufacturers to put extensive customizations on the OS. Some of the security features that BlackBerry advertises are fast response security patches, and full visibility into privacy settings.
From the BlackBerry Blog here are the main security features implemented into the device:
"Hardened Linux Kernel: We reduce the Android attack surface with numerous patches and configuration changes to improve security.
Address Space Layout Randomization: This feature scrambles application/system memory, making it more difficult for attackers to target your device.
Hardware Root of Trust: During manufacturing, we establish a Hardware Root of Trust that adds security keys to the processor on every DTEK50 and PRIV as it is built. Those keys track, verify, and provision each device – meaning that the authenticity and integrity of your device is guaranteed, as is the safety of the data it holds.
A Better Bootloader: Because of our secure boot process, you can trust that only an untampered, BlackBerry-signed OS can be loaded. Each stage of the secure boot chain must first verify that the next component is fully intact before proceeding.
FIPS 140-2 Compliant Full Disk Encryption: U.S. government-grade encryption protects your private information, like personal pictures or banking info, if your phone is lost or stolen." http://blogs.blackberry.com/2016/07/blackberrys-android-devices-such-as-the-new-dtek50-are-the-most-secure-on-the-market-heres-why-video-pics/
