Here is tier 2's list:
I'm using chapters 5-14 (as a lot of the chapters don't result in a level up)

+2 Shortsword (Table G)
Bag of Holding (Table A&B so Table B)
Scroll of Remove Curse (Table B)
Scroll of Spider Climb (Table B)
Chapter 6: Blingdenstone
Spell Gem of See Invisibility (though it will most likely be used already when the party approaches) (Most likely table B)
A lot of spell gems (they require sovereign glue which I doubt the characters have)
+1 Shortsword (Table F)
Spell Gem of Hallow (though it's a quest item) (Most likely Table C)

Analysis:
7 Magic Items from Table A
7 Magic Items from Table B
6 Magic Items from Table C
2 Magic Items from Table D
1 Magic Item from Table E
10 Magic Items from Table F
9 Magic Items from Table G
1 Magic Item from Table I
Table:
| What's given in OotA chp. 5-14 | Suggested in DMG |
Table A | 7 | 13 |
Table B | 7 | 9 |
Table C | 6 | 5 |
Table D | 2 | 1 |
Table E | 1 | 0 |
Table F | 10 | 6 |
Table G | 9 | 2 |
Table I | 1 | 0 |
So there are a lot less weak magic items and a lot more powerful magic items at tier 2.
