The drivers or whatever can influence the wireless experience a lot. Apple has the best bluetooth reliability of any manufacturer I've experienced. I can be out in a field next to my house and somehow the half-asleep laptop finds my headphones instantly unless I remember to switch its bluetooth off. On my windows machine sometimes, for seemingly no reason, you will be left standing around waiting and waiting for it to find the device right next to it.

The convenience of being able to get up and walk around the house, or got out with the phone without wires getting caught makes it worthwhile though. On the other hand for stationary peripherals like mice I would never go wireless. I hate that feeling of complete helplessness to the pairing/connection lottery and the time waste of it.
