When exactly? If you mean the Third Shinobi War, where Obito died "supposedly", the Konoha would be lacking one of the most talented ninja, while Obito would've still been caught in Madara's clutches, only some other way, since Madara's already put an eye on him. If you mean the battle against Kaguya, where Obito's actual death happened, again, Konoha would've lost Kakashi as one of the most valuable ninja and a future Hokage. As for Obito, it just would've given him some more time to help Team 7 out against Kaguya, but nothing more, since Obito's death after Ten-Tails extraction and Rinne Tensei use was already inevitable, as Naruto and Obito themselves realised, because Naruto's Yin-Yang powers managed to extend his livespan only temporarily.
