I find there to be five criteria when evaluating overtime options:

1. Prefer it to end quicker versus slower.
   
2. Prefer it to be fair to both sides.
   
3. Prefer it not to end in a tie.
   
4. Prefer it to encourage exciting finishes.
   
5. Prefer it to be traditional and feel like standard football.
   

Below is how the various options stack up compared to the criteria:

Old Rules - This one actually does well in most categories.  Being sudden death, games ended quickly and rarely ended in a tie.  Most games ended with a score which means an exciting finish.  It also obviously maintains tradition.  The issue is that it wasn't fair.  Getting the ball first was a big advantage and that was determined by a coin flip.  This unfairness grew with NFL rule changes that tended to favor the offense.

Current Rules - The change helped some with fairness, but hurt in other areas.  It's slower than the old rules and slightly increases the chance of a tie.  Games also didn't necessarily end in a score which sometimes took away the excitement.

No overtime - This option does well with fairness and is the quickest option to end the game.  However, it fails miserably with #3 as this method guarantees a tie.  I think ties are terrible.  Everyone walks away disappointed.  In many cases, this option may also not lead to an exciting finish as many games may have time expire with a team in their own territory.

5th Quarter - This option does well in fairness and feels like standard football.  However, it's the slowest of the options.  It also would be much more likely to end in a tie and may not have an exciting finish.

Old Rules but the team with ball first must score a TD while the other team only has to score a field goal - This option shares virtually all of the same benefits as the "Old Rules", but helps address the fairness issue.  The question is whether it fully addresses fairness.

Spot and Choose - Being sudden death, the games would end quickly, have an exciting finish and not likely to end in a tie.  I also find it to be fair to both sides.  If it has a weakness, it is that choosing the spot isn't particularly traditional as this doesn't happen anywhere else in the game, but that seems like a minor negative to me.  I find this to be the best overtime rule option.
