If I understand it correctly, SCORE means a WinRate with a 13.5% RoR with $10k. So they both have exactly the same RoR. The doubled speed of game 1 means that they now both have exactly the same WinRate. RoR and WinRate are usually the two things I look at most. So I'd say they were equal.
For the second question, don't you mean the second game was twice as fast? Obviously the first game, the way you worded it...
When we look at N0, we have to realize that it all comes down to total playing time. You still have an 85% chance of being ahead after 200 hours with an N0 of 20,000 @ 100 hands/hour, as an N0 of 40,000 @ 200 hands / hour.
