Thimble does what CodePen Projects does, allows you to have multiple files.
Thimble lets you upload assets.
Thimble has tutorial mode support.
Thimble shows the full HTML whereas CodePen's HTML panel is just for the <body>, and the <head> is in settings. For CodePen, it's easy to run into issues putting the <script> tag in the wrong place.
Thimble has one-click publishing a whole project that hosts the page not within an I-Frame. This would let it work on WebVR Polyfill and better for entering VR.
Personally, prefer the Thimble default UI with the code panel having vertical space.
Only downside is I can't find embed support on Thimble yet, but we can work around that.
