It does not have tabs. This is a UI choice that I actually like, although you have to get used to it. For me, tabs quickly become unwiedly. What I am usually looking for is “navigate forward” and “back”. Support for this is pretty good.
Regarding debugger, the Delve integration is good, although you will need to learn the JSON configruation format to specify your run configurations. If you need help with that, open a post about it here.
All in all, VS Code offers more out of the box, which is my style. The default git diff view is great. But hey, we’re talking editors here, so it’s everyone’s duty to fiddle with their setup. 
YMMV.
