Gowron's mod, while not being able to fix the bugs of the game, takes most (if not all) of the broken aspects of the game's design and re-works them into a more balanced system.
For instance, ships remain the same price when they upgrade, so no longer are you building your worst ship and upgrading for the extra cash and hoping no one attacks you while you do so. Instead you are always building your most technologically advanced ships.
Also, combat has been toned down so it lasts longer than 2-3 rounds allowing some real tactical battles.
Outposts are removed and instead there are 5 levels of Starbases. And starbases are the combat monsters they should be! While not indestructible, you'll need more than 3 cloaked K'vort's to remove them from orbit.
Industry has been toned down, an money made more available, so building to scrap for cash isn't as necessary to survive as in vanilla. Buildings and ships in general have seen an overhaul to be more useful and balanced overall through all the tech levels.
And finally orbitals and ground combat has been strengthened so you can't bomb out a whole system quickly, or overtake it with only a few cover ships and a couple of Troopships. A serious investment is required for planetary conquest.
Overall, the mod deals with all the major issues of game balance, and most of the minor ones too, and what's left is an far more playable and balanced version of BotF.
