I worked there for ~5.5 years out of college, I left a couple of years ago to try something else but I would say that it is worth it was worth it for me. Your experience is gonna be dictated big time by your manager and your manager's manager and there is wide variance on that across the company.

The average tenure there when I left was something like 18 months but there were many people in my org that had been there for years. I enjoyed working there but after working so much I wanted to relax a bit and felt like I had gotten all I could out of the company. The main benefit I got out of it was I was exposed to really big systems that need to be highly and highly responsive and learn how such systems get designed, iterated on and operated on in production (along with assorted best practices). At the bare minimum it equipped me to be able to handle any System Design Interview. That type of experience is not exclusive to them but easier to run into there.

I wouldn't worry about PIP, it is not as bad or prevalent as they make it out, the odds of you being put on it are really low. I only know of 1 person I worked with that was PIP'd. Everyone else was promoted from 1 to 2 and not all were rockstar developers. You really have to not give a shit or get really unlucky with a bad manager to get PIP'd. I also wouldn't pay much attention to what blind has to say, it is one of the most toxic places I've read.

Since you are going to be an SDE 1 it seems like you are a relatively recent grad? In that case I think there is no harm in stepping out of your comfort zone a bit even if you feel good about your current role. I can't speak much about how the finances, that depends on person to person, for some the extra money is not a big deal... others would literally sell their mother for a 10% increase in total comp, that's something you have to decide for yourself.
