Main difference (and main advantage) to other ISAs and VM bytecodes is probably that WASM has been built from the ground up with the requirement to run untrusted code safely (because that is absolutely needed for the web browser use case) while not 'leaking' any safety-related requirements up into the programming languages.
Anything on top of the 'WASM is just another ISA' idea is mostly just the usual Silicon Valley hype machine at work.
wasm gives you nothing more than any modern kernel. in fact, after you add the extensions required for your program to do literary anything, like accessing fs, network, etc, then you're out of wasm sandbox and back into depending on the kernel safeguarding you from the wasm host anyway. so what's the point?
