The full-size Shelly 1 Gen3 has one meaningful edge: broader integrations, since it supports Apple HomeKit while the Mini Gen3 does not, and it installs without a neutral wire, whereas the Mini requires one. Both are single-channel Wi-Fi relays with dry and wet contacts, hub-free local control, Matter support, and compatibility with Alexa, Google Home, SmartThings and Home Assistant. Choose the Shelly 1 Mini Gen3 for the cheaper, longer-warrantied, smaller relay in a box with a neutral; choose the Shelly 1 Gen3 if you need Apple HomeKit or a no-neutral install.
