When comparing GDevApp vs OpenBOR, the Slant community recommends GDevApp for most people. In the question“What are the best game engines for beginners and non-programmers?” GDevApp is ranked 5th while OpenBOR is ranked 30th. The most important reason people chose GDevApp is:
Prebuilt behaviors can be added to objects. This is a very efficient way to add a physics engine or make a platformer game. Lots of behaviors are included, from the most advanced (Physics, platformer, top-down movement) to really simple ones (like the behavior to destroy objects when outside the screen or the one to drag objects with mouse or touch).

Pro Quickly add behaviors to objects

Pro Powerful events system to create games without programming
No need for coding using this system which is clear and powerful: events are composed of conditions and actions.
Actions are launched when conditions are fulfilled. This is a very beginner-friendly way of making games and is still efficient for advanced usage, contrary to most other "block"/"drag'n'drop" systems.
Pro Intuitive interface
Pro Based on GDevelop
The entire webapp is based on GDevelop, an open source native game development software available for Windows & Linux, so it benefits from its advanced development.
Pro Can download an archive of the game source
Even though the tool depends on having a server up and running, you can download a copy of your game to run locally, or host somewhere else.
Pro Great UI
Sleek and user-friendly UI.
Pro Can export your game as HTML5 and for Android
Games can be packaged for Android without relying on any third party tool. You can also export your game and download it to host it on your server or let it be hosted on GDevApp.com.
Pro Shallow learning curve
Pro With a bit of tweaking, it's also possible to create a platformer
It's possible for a non-programmer who is comfortable with text-based designing to tweak the engine in order to create a platformer. Almost all the parameters needed can be found in the OpenBOR wiki, so it's easy to find anything a new developer needs.
Pro Great genre-specific engine
OpenBOR can quickly help create a good Beat-Em-Up game without programming.
Pro Great, supportive community
OpenBOR community is highly active and very helpful.
Con Depends on a hosting service
If the website goes down or closes down, you'll no longer be able to develop your games using this system (but you can download a backup of your game from time to time and open it with GDevelop).
Con Cannot deploy native games
For now, games developed with GDevApp can only be deployed for the Web. Android deployment is in the works, but even then, they won't be native since they are built with web technologies.
Con Text-based parametric editing
Heavy reliance on text-editing. No visual editor to edit characters and levels (although there are a few community-built ones that do the job).
