You must break down the part that led to that reputation.

Electron uses its own renderer (chrome). Meaning it can't share memory with the os browser and make download size way bigger. It bundles nodejs. Again make download size bigger Nodejs needs to create multiple processes which each of them can use a lot of memory. It use a bridge between the UI and backend (to do os stuff) while JS is nowaday fast, Go/Java/C#/etc are still faster

Wails on the other hand. Uses the os browser. (Download size is reduce and can share memory) Go is compiled to native, no runtime needed. (Download size is reduce, lower on memory, run faster) Same bridge performance bottleneck, but you can perform critical stuff in Go and get an advantage.

HTML renderers are fast. Code your UI with performance in mind, use a library like svelte or solidjs combine with something like wails (or anything that will do the same thing in java/c#/swift) and you won't see a difference between any native apps in most cases. Also you gain the ability to share your UI code with the web.
