In likewise manner, right now, Noah (assuming he is in the Book of Life) is resting by Abraham's side in Paradise (Luke 16:22 and 23:43). On the Day of the Lord, when those in Christ will be gathered up, and the dead in Christ will rise first (1Th 4:16), Noah will be taken over (paralambano) to the Heavenly Realm by God (--everyone whose name is found written in the book--will be delivered -Daniel 12:1).
Noah was not left behind when the Flood came. God had a special place for him and seven others in the ark. The ones left behind were all those outside of the ark. They all died.
Christians for the most part will not be left behind. Jesus has gone to prepare a place for us. Those that are left behind will suffer God's wrath and almost all will die. They will become "more rare than the gold of Ophir" --Isaiah 13:12.
The hang-up you are experiencing is focusing too closely on the word 'take.' Again, it reads totally different in the Greek and equating the two groups, those taken away in the flood with those taken over by angels does not mean the two groups come to the same end.
In each case, you have a rescue effort. In Noah's case it is the ark they had prepared. In the future case, it is the saving power of God through Christ Jesus where those that are alive and are left are literally snatched up.
In each case, you have the following wrath of God. In Noah's case it was the flood. In the future case it will be the seven trumpets, the first four working in thirds upon the earth and the last three being woes. The seventh trumpet shows the depth of God's wrath and is revealed as seven bowl judgments that work in total.
Do these analogies help?
