Garden office - mesh or Powerline

[TheresABearOverThere]

Hello, new garden office is insulated and wired and about 10m from house. Our WiFi doesn't reach there and didn't cable ethernet.

Does anyone have experience of using Powerline or Mesh systems for garden offices? What works best?

TIA for any insight.

Powerline , no question. Mesh could be patchy through walls. You'll get a more reliable connection with powerline.
