Is going for a YC startup a good decision?

Hey guys, I needed some serious advice, I am a SDE with 2 years of experience, I recently switched to a new mid sized company in Bangalore and the work culture is very good there are also good benefits, but there's nothing much in the learning perspective, I'm getting an offer from a YC startup for a founding team and it's in Delhi closer to my home but I'll also get a raise from my current and a hell lot of learning but I'm worried if it would be worth it? Leaving a stable company and going for YC?
