Atlassian .NET SDK, Atlassian SDK, Jira REST API

Hello!
I am developing a web application (.NET CORE C#, ReactJS). Do we recommend using the below SDK (Atlassian .NET SDK)?

Can I use the official Atlassian SDK (Getting started) for my application to get data from Jira Server (using c#), or is it better to do it using the Jira REST API?
