You really dont have much of an understanding of Tuning, not being rude but they can both be detected if BMW look hard enough, even if the tuning box has been removed they can see the boost values etc that are stored and would know that they are different to stock.
With ECU Maps you can now add or remove them in about 30 mins at home (anywhere in fact) and as such they are as invisible as a Tuning Box would be, in fact I would say a map is better as you dont even have to lift the bonnet and get dirty.
With a Tuning Box there is always a risk of breaking the connectors or at least the tabs that secure them.
I have had both and a map is in my opinion a better option providing you use a platform such as Bootmod3 or OpenFlash where you can remove at home.
If you have a Tuning Box and its removed BMW can still invalidate your warranty if they look hard enough. Don't be fooled!
