What is the difference between Spriggy and kit?

Could you please elaborate on the key distinctions between Spriggy and Kit? I'm particularly interested in understanding how these two platforms or products vary in terms of their core functionalities, target audience, and any unique features they might offer. Additionally, I'm wondering if there are any notable advantages or disadvantages of using one over the other, based on user experience or market positioning. Clarifying these points would greatly help me in my decision-making process.
