To some extent it depends on the type of aircraft you fly, and how much you value your hearing in years to come.
But mainly, the 'best' headset is the best one you can afford that suits you.
Go to a decent pilot shop, try them, see if you can borrow one you think you like for a decent length trip - a set that seems comfortable for a few minutes can be an instrument of torture after 2 hours - and then you stand a chance of making a wise decision.
