I've made lots of mods to it, I keep the Marlin firmware updated with many chances to make mistakes in the config files, and fiddled with stuff I probably shouldn't have ...  :P

Assume you mean Marlins own software rather than Crealitys software,  which I gather is a modified version of Marlin ?

As a beginner with an Ender3 V2, is it worthwhile installing Marlins own version ?  not sure what advantages it offers ?

Yes, Marlin from here -

Good question. It allows you to add features that the manufacturer did not enable on the menu of the printer. All the improvements / bug fixes in the underlying control software are also part of new versions. You can see all the changes in the release notes. Many don't apply to each specific printer but many apply to all printers -

https://github.com/MarlinFirmware/Marlin/releases

For example, one thing you can enable is something called Linear Advance, you can read about it here -

https://marlinfw.org/docs/features/lin_advance.html

You have to initially make changes to the Marlin-supplied configuration.h and configuration_adv.h files so all the machine settings specific to your printer are correct. You can probably find these config files for your printer available. If you can compile Marlin with those configuration files and get your printer working the same then you are all set. After that, you can move forward and experiment with items not enabled in the firmware supplied with the printer and keep the underlying control software routines updated.

I compile with Visual Studio Code -

https://code.visualstudio.com/

The binary file is written to an SD card and inserted into the printer's SD card port when the printer is off. When the printer is turned on and the printer sees a card with firmware.bin on it, it will automatically install the firmware. 

If you don't like tinkering with this sort of thing and your printer is working to your satisfaction, then I wouldn't do it. But if this sort of tinkering doesn't bother you and you can take a few failures and problems, then go ahead and go for it.

@xrunner  - thanks for your detailed reply, will certainly have a good look at Marlin, do not mind tinkering or compiling, half the fun , plus can always revert to Crealitys software if I get lost  ;D

Right - if you can get the firmware (binary file) from Creality for your specific printer you can just re-install that it if anything goes wrong.  :)

I found it in the original firmware also.
