Buying my first Ecoboost

Hi everyone, i'm about to buy my first Mustang soon, I'm thinking about a 2.3 ecoboost convertible from the end of 2017 or end of 2019. How reliable is this engine vs v6? I've read mixed opinons, some people says it's very reliable, great power, great fuel, some people say avoid at any cost as too small engine for such power. Ecoboost owners, what's your experience?
