They are identical. The listing that says Evoguide is wrong, it's an Evostar just like the other listing. From looking at the questions/answers both come with the standard accessories: aluminum case, dovetail, and mounting rings.
I recently got one of these scopes used here on CN and I'm really liking it so far. One thing that you'll probably want to upgrade right off the bat is the 2" adapter on the focuser. The stock one is kinda cheap and just uses a couple of screws which will leave marks on your gear. FLO sells an upgraded one with brass compression ring here: https://www.firstlig...ractor-m54.html.
You can probably even get the scope itself a little cheaper from FLO if you're willing to buy from overseas.
