Can someone spoonfeed me on the benefit of using tavern with pyggy collab as opposed to just using collab pyggy when you have a potato pc? I want to try out pyggy, but using just the collab has recently made json files not work, and I don't know if tavern would fix that, or if my potato can even handle tavern due to me not knowing the difference in requirements. I am an idiot. Please help.
