I don't know what the OPs mum is like but of it was my mum the ease of use for the firestick is what pushes it for me (although I have supplied her with a mag box now but the OP wanted entry level pricing). I have had, and still have, a variety of boxes ranging from Android boxes and firesticks through to the Nvidia Shield Pro (amazing bit of kit, wish I had got one sooner) and in terms of value and simplicity of use I personally prefer the firestick.
