I use pea protein as I'm lactose intolerant. The taste was pretty bad at the start(like concentrated peas) until I realized I wasn't adding enough water. Added more to make it more diluted then it just tasted like a less flavorful choc protein shake.

Didn't feel bloated or gassy compared to whey protein.

In terms of pros and cons, as long as it helps you hit your daily protein requirements as a supplement you should be fine.
