“The RPi5 is a worthy upgrade to the previous version. The desktop experience with Raspberry OS is much more fluid and smoother. It delivers a strong performance and adds features like faster DDR4, on/off button and dedicated Fan Header, PCI-e interface and faster MicroSD speeds. In the longer term, I'd recommend the Pi5 as the difference in price to the Pi3/4 justifies buying the newer model (for projects that require higher-spec hardware). If you have older hardware that runs well (e.g. Home Assistant) I don't think is worth upgrading for now (IMHO)”
