Lion's B,F+K

I'm returning to the game after 13 years away and have picked up a lot of what I forgot. I'm finding a good use for most of Lion's moves but I never use his B,F+K move. U+k, k is a quicker and more reliable way to beat opponent's crouching punch, and the move feels a little slow to be useful in most situations. I feel like I'm missing out on potential damage here as it does lead to a decent damage combo, but can anyone tell me with when it's good to use and any specific situations?

 

AFAIRemember, Lion lacks quick mid launchers that don't require a CH to launch, 46K kinda fits that niche. It's got decent range, if it is more like Jeff's 4K+G than I remember it has a good hitbox, and can be used to punish whiffs. So it may not have the almost instant airborne frames of 8K, it serves a different purpose entirely. Though if you have a P blocked or have +frames from blocking an attack, it will beat the low (probably? I don't play Lion).

Post dojo edit:
Also because of it's ability to be done with a backdash input, you can beat predictable 2P when at disadvantage too.
