I think they are all the same, just different interpretations of the G.A.U (Grand Architect of the Universe), the Divine, Creator, etc. Whichever name fits best; "God", Tetragammaton, the list goes on and on.
any deity really, its whatever one speaks to you. i have zero Egyptian in me but i worked with various Egyptian deities for years. my current deity is Celtic. looking into your ancestry and researching the ancient culture can sometimes help us find our patron deities, it's not a key factor. think about what you like, what are your hobbies, your personality, your favourite animals or colours, do you feel more at peace surrounded by a particular element? is there a culture you're fascinated with? these can narrow it down further.
another thing you should do is observe the world around you, while meditating do you feel or sense something? is there reoccurring themes you see in your dreams? do you come across a certain animal, or see repeated items [like sea shells, numbers, crystals, animals...] in your daily life? all these things can also point you in the right direction.
