Interesting list... I would have expected the price points to be similar since you are comparing, but they aren't or shouldn't be.
Row 15 is the very last row in the balcony. It's not bad if it's truly center court; Sections 315-317 or 330,301-302.
Row 23 is too far back for SEC 6 or 7; it would be okay if you were in 5/8 the corners. The problem with these seats is lack of depth perception. When a guy shoots a 3 pointer it doesn't look that much different than when a guy shoots a free throw.
The sports deck is even further behind and higher up than SEC 7 Row 23, but you get more space and food.
I'd probably go with balcony center court as first choice and especially if you are there to watch the game.
Second choice would be the deck since it's more comfortable seating and you get food.
Last choice would be SEC 7 since you are already about 3-4 rows from the back. Might as well go up a level to enjoy the ameneties of the deck.
