ARMv7, ARMv8/9, PowerPC are nearly finished, and MIPS in in near-term plans. Nobody stepped in for RISC-V yet.

I was curious about these libraries a few weeks ago and did some searching. Is there one that's got a clearly dominating set of users or contributors?
I don't know what a good way to compare these might be, other than perhaps activity/contributor count.

I'm the main author of Highway, so I have some opinions :D Number of operations/platforms supported are important criteria.
A hopefully unbiased commentary:
Simde allows you to take existing nonportable intrinsics and get them to run on another platform. This is useful when you have a bunch of existing code and tight deadlines. The downside is less than optimal performance - a portable abstraction can be more efficient than forcing one platform to exactly match the semantics of another. Although a ton of effort has gone into Simde, sometimes it also resorts to autovectorization which may or may not work.
Eigen and SLEEF are mostly math-focused projects that also have a portability layer. SLEEF is designed for C and thus has type suffixes which are rather verbose, see https://github.com/shibatch/sleef/blob/master/src/libm/sleef... But it offers a complete (more so than Highway's) libm.

An interesting point here is that AES-NI can be used to accelerate a host of things other than AES. In this case, it's because the S-box can take advantage of the AES S-Box (SubBytes) instruction: https://github.com/jkivilin/camellia-simd-aesni; https://kernel.googlesource.com/pub/scm/linux/kernel/git/sha....
Similar acceleration has been done with SM4, the Chinese analogue of AES. https://github.com/mjosaarinen/sm4ni
