Even the premium Samsung devices are often slower than some brands when it comes to security updates. My Android 11 phone gets its security updates every month around the 5th of the month but then its a different brand. If you want 'bleeding edge' in terms of Android versions and security updates it comes down to which brand you choose. On a more helpful (and relevant) point though, is there any real reason why you NEED this right away? Even though my phone gets updates lickety split every month or when Android updates are released, I dont think I've ever needed to use those features as soon as they became available.
