Comparison between LoadRunner and Astra LoadTest

Hello All!
I have some questions for you to answer them for me.

1 With respest to testing web applications, what are the features extra in LoadRunner when compared to Astra LoadTest 5.4.3.?

2 For testing a web application, is Astra LoadTest enough to meet all the required test scenarios? If not, then what are those features that cannot be tested using Astra LoadTest?

3 Our client application is developed using Win socket protocol, and the application sends HTTP requests to the Web server about the login and other status of the user. We therefore may have to use dual protocol HTML/HTTP and Win socket, which is possible in LoadRunner. Is it similarly possible using Astra LoadTest?
