I didn't try Headlamp, but I moved to AptKube from Lens and been happy since then. It might not be a best in class, but it is snappy and doesn't require any cloud accounts.
There is no free version and comparing to something like Jetbrains IDEs price is a bit high for such a small tool. It is made by a single dev in a market where not that many paying companies, so higher price is understandable.
