Depends on the type of person you are, I found Uni an excellent means of developed life and social skills, and I was able to gain some experience living more independently. If I had chosen not to go, I couldn't guarantee that I'd have experienced these benefits, certainly not to the same extent. But that's just me. Others may be different.
Putting aside the seriousness of it all, it can essentially be the most enjoyable, fun few years of your life. Not just fun in a literally sense - parties, clubs, a group of friends gathered round a BBQ on a summer's evening - but fun in that it can be challenging. I studied Economics which got rather hard at times, but it was a love-hate relationship. There's certainly a great level of satisfaction associated with studying complex stuff and understanding it, and hopefully demonstrating this understanding. Obviously, this will depend on you - and what you are studying.
Depending on how you are accomodated - you might find yourself making some really great friends too. They say your life-long friends are the ones you meet at Uni, and largely that is true. You tend to form strong bonds with those that you are with, all together tackling something new and challenging. I'm very grateful for the friends I have made.
So yes, I strongly recommend it, but I stress it depends on the type of person you are and what you'd be studying. A degree might not necessarily land you a dream job, but it still makes an excellent qualifier.
