Personally I find quantum computers really impressive, and they havent been given its righteous hype.
I know they won't be something everyone has in their house but it will greatly improve some services.

One problem with QC is that besting classical computers has been a moving target, improving exponentially for many years while QC was being researched. It's going to be a long, slow climb up the slope of enlightenment as it reveals its potential.
Well, yes and no.
Quantum computers will likely never beat classical computing on classical algorithms, for exactly the reasons you stated, classical just has too much of a head start.
But there are certain problems with quantum algorithms that are exponentially faster than the classical algorithms. Quantum computers will be better on those problems very quickly, but we are still working on building reliable QCs. Also, we currently don't know very many quantum algorithms with that degree of speedup, so as others have said there isn't many use cases for QCs yet.
Kind of like cpus and gpus perform radically different depending on what's fed into it.
