6k or 3k Which kick is "better"

So still new at this game, I understand the frame data..ok..sorta; but which of the 2 kicks is better/practical?
6 or 3??

I think 6 is better to get a counter hit
while
3 is a better poke
correct?

What are your thoughts on these 2 kicks and their potential?
Which one should you use more often (better combo potential)?
What are their strengths and weakness?

Help a newb!!

 

is half circular, it will hit people who try to evade in the wrong direction.

 

I like 6K's crumple, but I admit I haven't used this move too much in my game, whereas I've used 3K for the half-circular, as a range poke, and to punish backdashing.

That said, this does not mean 6K is neither of these things, because I honestly have not used 6K enough but it's on my list of moves I do want to experiment with. For example, while 6K looks shorter, I have not verified that and I think it's important to know that. Maybe it's a better backdash punisher because it will crumple, need to see if the range is sufficient. And there are more questions I should look into answering with 6K.

In any case, my impression of 6K is that I like the move, I just need to spend time trying it out and fiddling with it in my matches to see how it plays out. I have used it a bit here and there, and I will admit on those rare occasions that I use it, I do get the crumple combo--so it's definitely won a lot of points with me. I'm looking forward to seeing what I can do with this new attack ^_^

I am comfortable with 3K because it is familiar and its range and half-circular properties make it quite useful in certain situations. But 6K is new and will take a bit of time and pushing to see how much mileage I can get out of it ^_^

 

Hmm what's the connection between those 2 moves (beside that they're both kicks)?
One is a mid-long range half circular poke (and one of lion best moves)
and the other is a combo starter on CH

 

I don't see a lot of instances where 6K would be better than 33P.
One of those is when you're fighting a char that can sabaki mid punches (Aoi, Vanessa...)
That's how I use it.
