iara VS liblava

Sorry for late response! The one I like most is LibLava https://github.com/liblava/liblava I contributed a few features that it was missing for me, and a few other people have done the same, so it's somewhat battle tested. At least two people have used it in academic projects. I like that it gives you full access to the low level parts of Vulkan while still providing high level abstractions over a lot, especially the render loop. The biggest issue imo is lackluster documentation, but it's fairly well organized and readable source code. Build times are also pretty long due to its many dependencies.

When I was pretty new to C++, I made some contributions to liblava, because it was missing features I wanted to use. Exploring its codebase taught me a lot about perfect forwarding, template metaprogramming, and Vulkan. I think it's a pretty nice modern codebase, if you're interested in graphics. There are some open issues for feature requests, and the maintainer is very friendly.

Until your users start complaining about the performance. If setting up Vulkan is your pain point (which, I can understand, it's a verbose chunk), libraries like liblava provide a very nice abstraction over things.
