Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

xPro V5 vs CNC shield vs others?
The BTT SKR is a 3D printer controller using a 32-bit LPC (Arm, baseically) micro, so it'll easily support 4 axes and have plenty of leftover power/expandabilty. The main gotcha could be spindle control, but... hm, yeah, the source indicates that they just use a heater MOSFET for spindle PWM, so it's not going to be much different from a stock 3018 controller.

Electronic leadscrew, or full CNC?
And it looks like pendant support was 'enabled' last year in grblHAL, but I don't see the "I'm with stupid guide" that I would need to connect it.

Budget budget CNC controllers - what's the bottom line?
You might want to look at grblHAL. It is the 32-bit evolution of Grbl. I make a 5 axis breakout board for it based on a Teensy 4.1. It supports step rates up to 400 kHz which allows you a lot of freedom in selecting microsteps and high speed rapids. All in with the Teensy, it costs about $65-70, depending on options. Here is a gallery with a number of machines based on grblHAL. More about grblHAL here. It is actively being developed with people adding features and porting to new processors (RaspBerry Pico is coming).
What are some alternatives?

BTT_SKR_13_14_14T_SD-DFU-Bootloader - This is a repository of BIGTREETECH bootloaders. The originals are stored under the bootloader_bin/backed_up_original_bootloaders/ directory. This repository also has a bootloader for the SKR E3 TURBO to fix the high pitch sound coming out of the CR10_STOCKDISPLAY it is located on the bootloder_bin/compiled_bootloader_bin/ directory.
