Well, they have some differences :
- The size : 29" ( Sony ) vs 21".
- A consumer product ( Sony ) vs a professional monitor.
The Sony comes with several kinds of inputs ( Scart, S-VHS, component to avoid at all costs ) very useful for retro consoles especially scart which is RGB capable, the best video quality.
Even if it's not a professional CRT it's a good choice for retro gaming as it can display beautiful images. Lots of settings are available in the service mode menu.
What do you intend to plug on your CRT ?
I didn't find information on the Barco monitor. As many other professional monitors it should have BNC inputs, not sure for a scart connector. It should display great images as well.
Hope This Helps.
