I love Astrill. I've been living in China for the past 3 years and for the first two, I was using Witopia. It was alright, but nothing compared to Astrill when I got a free trial from a friend. The best thing about it is the interface; a simple one-click to switch on or off. I don't have to wait minutes for it to find a server and so on and so forth. Sites like Facebook load very fast, and my connection isn't interrupted at all which is also a plus. Youtube videos do happen to load somewhat slow, but they get there eventually. For those going to a place with restricted internet, especially China, I wouldn't use any other VPN. Period.
