I have questions about Lee Sin

Hello people,

So I am trying to get used to Lee Sin in S6, as they are new changes that I'm pretty sure effected every single champion in this game. As I see what is the optimal build for Lee Sin, I see many differentiation of builds from people mostly in the type of smite. Does anyone know how to answer my question on what knife is most optimal, not just for me, but the community too and maybe I could start a discussion on this as I have tried all three and I do not have a preference honestly?

Jungle Knives: I see people getting Stalker's Knife/ Blue Knife (for anyone not aware of what the jungle items are) for ganking, Poacher's Knife/ Green Knife for the extra utility and ward hopping ability, and even the Skirmisher's Sabre/ Red Knife. All three have their uses like Skrimishers for 1v1ing the enemy jungler, but I am wondering which one is most preferable by everyone. All of these have their downsides which I straightup dislike, especially from the Stalker's Knife.

Stalker's Knife: It is great for ganking for me and I have two slows along side with my E and a displacement with my R. But I am kinda forced to get a sightstone unless if you want to rely on your trinket and it becomes more and more useless as the game goes on. To be honest, I am kind of leaning towards this one because I love snowballing myself and the lanes and this Knife can do it easily. Unfortuantely, the downside holds me back from buying this %100 of the time.

Poacher's Knife: I have more utility in general and vision, which allows me to do more plays to the enemy (especially their junglers that can not fight me). But I do not feel as strong as I could be with the other knives and I am kinda forced to just kick people and limit me a bit on who I can fight. Like I know that Lee Sin does a HUGE amount of damage early on, but I feel like the other knives kind of spices up his damage. Also, my yellow trinket could also provide a similar result too at times.

Skirmisher's Sabre: Makes me feel like an almighty beast that just wants to ALWAYS want to hit their second part of their q, but I am lacking in utility and just have raw damage which is bad for Lee Sin late game. I can always go tank though and go for insecs which is a good way to negate it, but somewhat not enough. I have not used this item as much as the other two, but I have seen people in my games and people like NightBlue3 use it.

Side Note: Also, Lee Sin is so much fun and anyone who wants a new jungler should practice him, you can be so ballsy early on and get away with it. Do not give up in the beginning as Lee Sin is very technical and I have been playing him for around 6 months and I still miss my q's. This post is meant to help me and also provide insight for other people who plays Lee Sin and could cause a nice discussion too.
