Hague linker or overlock sewing machine for? Or both...?

Hi everyone!

I’m seriously thinking (and collecting money) about buying a Hague linker or an overlock (serger) machine. I need it for faster sewing up knitted pieces… But I want to read about your experiences, do you have linkers or sergers, what is in your opinion better for faster sewing up knits…

Many thanks for your replies.
