gradle.properties vs buildscript ext which one is better

Question

gradle.properties code snippet

APP_BUILD_COMPILE_SDK_VERSION=28
APP_BUILD_TOOLS_VERSION = 27.0.3

APP_BUILD_MIN_SDK_VERSION = 16
APP_BUILD_TARGET_SDK_VERSION = 28

supportLibraryVersion = '23.4.0'
playServicesVersion = '9.2.1'

buildscript ext code snippet

ext {
    // sdk and tools
    minSdkVersion = 14
    targetSdkVersion = 23
    compileSdkVersion = 23
    buildToolsVersion = '23.0.2'

    // dependencies versions
    supportLibraryVersion = '23.4.0'
    playServicesVersion = '9.2.1'
}

I've used both in my different projects but anyone knows what is the best difference of them?

Extra properties is a special extension of type ExtraPropertiesExtension added with name ext.

Properties passed with -P command line options or added to gradle.properties file are added to the extra properties extension. They’re simply added to one of existing scope
