Eh, I had a much better experience. But I don't chalk up my success to HR's curriculum nearly as much as I do the people (though getting exposure to Node.js has been a huge aspect of my life).

If you're going to any bootcamp/immersive and you're going for the curriculum all you're going to get out of it is the curriculum - which you could easily obtain from freecodecamp.com for... well... free. If you're going to go, you should be going for the people - your sprint partners, thesis groups, beer buddies, outcomes teams, tech leads, alumni network... that's what lasts after Hack Reactor and it yields dividends well beyond the (admittedly striking) sticker price.
