God and god is same and a title

Do you know that the English word god comes from the Old English god, which itself is derived from the Proto-Germanic *gudą. Its cognates in other Germanic languages include guþ, gudis (both Gothic), guð (Old Norse), god (Old Saxon, Old Frisian, and Old Dutch), and got (Old High German).

According to dictionary definition, God/god means:
(in Christianity and other monotheistic religions) the creator and ruler of the universe and source of all moral authority; the supreme being.
2.
(in certain other religions) a superhuman being or spirit worshipped as having power over nature or human fortunes; a deity.
"a moon god"

Note: search for the meaning of monotheistic.
The term God/god is a term used by English to refer to the deity of monotheistic religions.

The development of English orthography was dominated by Christian texts. Capitalized, "God" was first used to refer to the Abrahamic God and may now signify any monotheistic conception of God, including the translations of the Arabic Allāh, Persian Khuda, Indic Ishvara and the Maasai Ngai.

I will save some of my explanation.
My question is,

As a member of a monotheistic religion, do you think it's good to call the deity of your religion by a term used to describe deities of different monotheistic religion, or you think it's better to call the deity of your religion by the name he called himself in the language of the people they choose for themselves?
