Christianity is limited to the economy of salvation, because it forgot its metaphysical roots. It dropped gnosis, that was developped by the scholastics, the ordos templis (and other secret orders) and the first christians.
Islam have kept this esoteric components, through cufism. That makes islam a complete tradition, which is not Christianity.
So metaphysically, Islam is far far more profund than christianity (technically, christianity is profund too, but you have to do all the work from the start of searching for the old books, the real heart of christianity that have been lost, not making mistakes etc… that's very hard).
On the matter of Jesus being a god, well, there is one ultimate god which is the center of everything. Trinity is a mistake. The metaphysical definition of infinite, which is the most important characteristic of god is the absence of limit. That's why a mathematical sequence cannot be called infinite as it is in modern mathematics, because the definition of the sequence is a constraint, and a contraint is a limit, thus going out of the definition of metaphysical infinite (a more appropriate word would be "undefined").
Therefore, defining a trinity, with multiple part taking together making one god is logically false. Because if makes the trinity none infinite.
Finally, you shall chose islam because islam is the religion of the end of the world. That's why it has such an preeminent position in the middle of other traditions (corrected obviously). That's why staying a chritian even if you follow you true original metaphysical roots would not be sufficient.
By the way, you don't have to start other in Islam, the road is already here, so that's far easier to have a real profund spirituality.
Most people that god the spiritual light lightened in their heart first chose buddhism, but then and finally end up in islam and cufism. Because that's the easiest door to initiation.
