Festool is good if you can eat the cost and in my opinion they are not that much better than alternatives. Hilti is absolutely beast, but their pricing is pretty much "if you need to ask you can't afford it". Metabo owns also Hikoki tools and they are pretty good based on a limited personal experience.
But I'm spending my own money on Makita. Good tools and since I already have a bunch of their batteries it's pretty easy to choose brand. With wall power or air I don't have any brand loyalty, depends on the tool and how much I need it for.
