ADK reed diffuser or aromatherapy candle, which is better?

Compared with scented candles, reed fragrance disperser keeps stable fragrance in a certain range, which is safer at ordinary times. I feel that aromatherapy candles are more ceremonial and warmer when lit in certain seasons. Generally speaking, it is mostly spiritual satisfaction. If you care about safety, I think reed diffuser is enough. In fact, there are many things to light aromatherapy candles. In order not to make the candle uneven, how long does it take to touch the wax for the first time? In addition, if you don't buy candle tools, there will be black smoke and smell when you put out candles.
