Dealing with types is boring so if I'm going to spend time on this, it should have enough benefits. In my humble opinion the rust typing system is more interesting than what typescript can offer.
The main advantage for me is the monad. Sure you could use monads in typescript or even vanilla javascript but in Rust, everything uses monads.
The vast javascript ecosystem is available to rust in the browser too. Server side it's not as big and I agree javascript has a point there. But now, if you look at the ecosystem of libraries with proper and up-to-date typescript definitions, well it's not that great.
