Managed hosting, is it worth the extra cost??

I've used shared hosting up until now and due to increase in site traffic I'm switching to VPS but managed services costs.. 50-100 dollars while the server is around 10 dollars,
For those of you who've switched, do you feel like it saves enough time to justify the extra cost, or do you still end up doing most of the work yourself?
I guess with AI it's a lot simpler to manage and be aware of the Linux commands, but I'm worried my site will crash and I won't know why.
