Not better but different. The reverse flow plate evens out the temp across the body of the smoke chamber. If designed properly the smaller chamber (>250gallons) are easy to manage.
The difference from a traditional offset, is that you loss the dual zone hot spot ability. On a traditional offset, the firebox side is significantly hotter than a reverse flow. I've used both, when you are comfortable with either you can produce some amazing 'cue.
