I've been pretty happy overall with my Arc A770. For the price, it performs well, and driver issues are mostly a thing of the past. My only complaint is that the anv Mesa driver doesn't implement VK_NV_device_generated_commands which appears to be a requirement for some D3D12 games on Linux (Starfield being the one I had issues with). Luckily, it looks like there is a new non-NVIDIA specific extension to solve that and an open MR in the Mesa GitLab to add it to anv.
