Naturally if you aren't satisfied with an R/T it would be a logical step to upgrade to the SRT... but we're also talking several thousand more $ and a much more limited color selection if you go that route. I'm not a drag racer either, but with an R/T I should at least be able to hold my own against an unmodded base-model Mustang GT if one rolls aside at a stoplight instead of having to lay low for fear I'm gonna get majorly spanked.
