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.

Differ: Tool for testing and validating transformed programs
Differential fuzzing is woefully underutilized -- our experience is that it consistently[1] finds[2] bugs that "traditional" fuzzing techniques struggle to discover, and that the primary obstacles to its adoption are harness and orchestration complexity. DIFFER goes a long way towards overcoming those obstacles!

Just released v0.2.0 of bddisasm - a no_std x86/x86_64 instruction decoder which aims to provide as much information as possible about an instruction
You may also want to check mishegos for another way of comparing different decoders.

Is Ghirda's Disassembly ASM output accurate enough?
Take a look at something like mishegos to see how sometimes the same instruction will be decoded differently by different disassemblers: https://github.com/trailofbits/mishegos

It sounds like what you want is Mishegos [1], described here [2].

Pros and Cons of Rust for Cybersecurity
But, due to the young ecosystem, Rust isn't often the best choice for the 2nd category. There are exceptions: while working on a ROP exploitation CLI tool, I was surprised to find the top 3 fastest x86-64 disassemblers are all written in Rust. But other languages just have more mature security ecosystems. Python in particular has some amazing libraries like scapy and bindings for yara.

I hate to be that guy, but I want to mention the disas-bench project, a open-source benchmark for various disassembler libraries, including bddisasm.
What are some alternatives?
sandsifter - The x86 processor fuzzer
bddisasm - bddisasm is a fast, lightweight, x86/x64 instruction decoder. The project also features a fast, basic, x86/x64 instruction emulator, designed specifically to detect shellcode-like behavior.
capstone - Capstone disassembly/disassembler framework: Core (Arm, Arm64, BPF, EVM, M68K, M680X, MOS65xx, Mips, PPC, RISCV, Sparc, SystemZ, TMS320C64x, Web Assembly, X86, X86_64, XCore) + bindings. [Moved to: https://github.com/capstone-engine/capstone]
yara-python - The Python interface for YARA
xgadget - Fast, parallel, cross-variant ROP/JOP gadget search for x86/x64 binaries.
scapy - Scapy: the Python-based interactive packet manipulation program & library.
