KJs73.6342.42823.93874.848
QJo23.9382.42873.63425.152

The first hand is a suited hand; the second is an offsuit hand. The two hands share a rank, and the one with the better other card dominates: it wins most kicker battles when that shared rank hits.

That is a clear edge, 74.85% to 25.15%, but QJo still wins often enough that one hand proves nothing. 2.43% of boards are ties, so the equity of each hand is its win rate plus half of that.

By strength against a random hand, KJs holds place 20 of 169 and QJo holds place 39.
