The question for anyone using them for other than personal use may be long term reliability. My three Soekris 4501s all died from power supply failiurs after 5 years contnuous use, while the 4801s have 6 years under the belt and still going strong. Will the RPIs and BBBs systematic issues or still be running after the same time? Of course 5 years is not that bad when S1 NTP servers are dedicated to that. Also the cost is so low that replacement isn’t a problem. A no brainer really.
