“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)”
“Looks great, and seems to be perfectly functional as an upgrade to the Raspberry Pi 4, though as I have only received this it will take a bit more going into to get the most out of it.
The OS can be a little flaky as after installing this I lost the menus, but now have them back, this is the first time I have experienced this on a Pi.”
