In app engine it tells me my URL is projectname.ll.l.appspot.com but if I use projectname.appspot.com that works as well. Which is the correct one to use and why?

App Engine is changing the URLs that you use to send requests to your apps. project-id.appspot.com is the default URL, however if you have multiple services and/or versions, each of them will have its own URL.

Which is the correct one to use and why?

Both are correct, however moving forward you may apply the suggestion from this release note:

App Engine is changing the URLs that you use to send requests to your apps. URLs now include a region ID to help Google route your requests more efficiently and reliably. For example, an app can receive requests at https://PROJECT_ID.REGION_ID.r.appspot.com. This new URL is optional for existing apps and is provided for all new apps.

You should register your own domain and use that. The cost is only $12/year so it is affordable even for a hobby project.

If you don't want to do that, then use:

projectname.appspot.com

because it is much easier to type.

It is possible (though I think unlikely) that this link will stop working at some point and you will need to change to projectname.ll.l.appspot.com . If that is an issue for you, then pay the $12/year to get your own domain.
