Playing Sit and Go offers a more stable structure, with gradually increasing blinds and chip stacks. This allows for a more strategic approach, with more time to make decisions and develop a game plan. Also, the presence of other regular players can allow for a more accurate reading of opponents.
On the other hand, playing Spin & Go offers the thrill of big payouts and the possibility of winning big in a short amount of time. However, the accelerated structure and random nature of the draw can lead to higher variance and require quick adaptation to different situations.
