I can attest that my Pixel 3a received the February update as soon as it was released directly from Google, and I have been overall very happy with this phone. Pixel 3a is the cheapest yet (IMHO) best Pixel phone on the market. It is guaranteed to receive OTA updates and security fixes until at least May 2022: https://support.google.com/nexus/answer/4457705?hl=en
