This is just my opinion, let me know what you think!   

i think sicilian is #1 an e5 is #2

also pirc is pretty much a slightly more flexible modern defense so i would put it as #7

I would definitely rather play the Owen defence than Alekhine. To me that's just asking to have your knight chased around the board. Maybe good players can get away with it but I wouldn't want to start a game like that. Or a hippo setup, I would take that over Nf6 to e4

The St. George defense (1...a6) is a serious opening that is much better than it looks at first glance. I don't even know what the Ware or Carr openings are, but St. George probably derserves to be higher then them.

1. Sicilian

2.e5

3.Caro-Kann

4.French

def not better than the caro but probably better than ware

Carr, not Caro lol.

I'd give a tie for e5 and Sicilian and switch Alekhine and Nimzowitsch but I'm biased

That's how I would rank it 

#1 St George and Polish

#2 Carr and Borg

#3 Goldsmith 

#4 Ware 

#5 Nimzowitch and Lemming

#6 Kings Pawn (1.e5) and Barnes 

#7 French

#8 Owens

#9 Caro-Kann 

#10 Modern 

#11 Scandi

#12 Pirc

#13 Hippo

#14 Sicilian

#15 Alekhine and Duras

This might be the worst list I have ever seen.

haha??

Tier 1

 Sicilian, King pawn    

not only objectively really good, but immensely flexible which is very important.

tier 2

French, Caro kahn,   

Objectively as good, but not as flexible , slightly harder to play for win with uncooperative opponent

tier 3

Pirc/modern, Nimzowitsch, Owen, Alekhine, Scandinavian  ( no order here, too hard to judge)

objectively take longer to equalize and black walks in narrow corridors in critical lines. Usually not flexible at all , (or when they are flexible, the sidelines are not objectively that great), but black at least gets a fighting game in a lot of these lines

Tier 4 

St george

It has independent significance, but simply isnt as sound as tier 3. 

Tier 5 the rest.

most defenses here have no independent significance or are a joke. They also tend to weaken black's structure. Interesting the Borg 1.g5 has the most independent significance with at least a sort of structure to go for, but is simply objectively terrible, and worse than most of the other defenses if white plays well.

why?

It's crap to everyone.

This is my list based on personal preference/how comfortable I am playing the openings. For the objective quality of the openings, darkunorthodox's list sums up my thoughts exactly.

1. Nimzowitsch

2. Alekhine

3. French

4. Scandi

5. 1...Nh6 and 1...f6

6. Owens

7. Caro-Kann

8. St. George

9. Pirc and Modern

10. Duras Gambit

11. 1...g5 and 1...h6

12. Sicilian

13. 1...e5

14. All the other junk (1...b5, 1...h5, 1...a5, 1....Na6)

Why don't you give me your reasoning? It looks to me like you randomly placed them with absolutely NO thought for opening principles and master play. I want to know how you will justify it before responding.

Barnes might be the worst of the worst!

Or maybe just b5…
