of those two - the flying bear.

It's a solid looking build, as far as I can tell.
It looks like a bowden extruder, but should be fairly easy to convert to a direct drive.

Standard Wifi is pretty much useless on a 3d printer.
I've got 2 with wifi - neither does anything useful.

So it depends on the firmware on the wifi module.

If you can upload a file direct to the sdcard and then get the printer to run it, via wifi. It would be really useful.

But anyway - mechanically the flying bear is the better machine.
Most of the parts are very similiar to my sapphire pro2 - but without the corexy.


And as I keep repeating - to a large extent you get what you pay for.
The ender series is cheap for a number of reasons. None of which are in the end users favour.
