I'd go with the Limitless for increased capacity and more airflow. I love how solid the Avocado 24 feels, but I'm not a fan of its miniscule fill port. You can definitely tighten its draw to a MTL or DTL it as well. I love the flavor it produces. I have not used the Limitless just yet, but I imagine it's similar to the Limitless XL, sans leaky bottom airflow.
