I think they both have their places.
There's something meditative about going through the actions of actually packing a bowl or rolling a joint. It's methodical, let's you get into a good headspace. It's more a full body experience.
Using a cart or even hitting a dab rig, you're using more tech, there can be more of a convience to it, but you lose out on the time spent with yourself. You lose out on the ritual, the spirit of it. Sometimes it's nice, but sometimes, nah, I want that nice practice, the ritual of preparation my way.
