The 30mm tube has nothing to do with light. It gives you more adjustment for long range shooting.
The 50mm lense is only helpful in low light up to 10X, above that it won't let in any more light than a 40mm glass set on 8X. The 56mm lense will allow you to go up to 11X.
If you've got the money the Swaroski will most likely have the better glass and be better on all magnifications.
But you're over thinking this. The difference between a $300 Leupold and a $3000 Swaroski is about 5 minutes more shooting time before both are useless.
