What are the differences between nitro and CO2 in terms of their use in pressurizing beverages?

Nitrogen (nitro) and carbon dioxide (CO2) are both used to pressurize beverages, but they have different effects on the drink. Nitrogen creates smaller bubbles, giving a smoother and creamier texture, while CO2 creates larger bubbles for a more carbonated and fizzy drink. Nitrogen is often used in stouts and ales, while CO2 is more common in sodas and sparkling drinks.
