Both fridges are nice with the Liebherr having more options. Your choice on Liebherr is for a custom panel unit while Fagor has stainless or black as their only options.
Service support and parts supplier is the same company for both brands. They will handle selecting a repair company in your area if needed.

You might want to look at Blomberg as another option. They have expanded their sales and service area to East, West and Midwest of the country. Blomberg and Fagor are a closer comparison in price and value than Liebherr.
