How would the back corner of Gamma be any farther away from home than the back corner of Delta? The distance from both locations to Earth is identical; sailing for the Gamma end of the wormhole would not take our heroes farther away from home, even though it would be wasted sailing. It would just take them to the same distance they started from, after which it would be their choice whether to sail directly for home, or first sail back to Delta to avoid encounters with the Jem'Hadar.
Because a straight shot from the Gamma side of the Wormhole, would take you through Galactic center, so, you have the extra distance going around Galactic Center, you don't have that issue with Kazon Territory, because you're already on the outer edge

Where are we going? And why are we in this Handbasket?
