Is there too high of a sensitivity? Or too low?

This is something that I think a lot of players wonder, and adjust their sensitivity because of it. Some worry their sensitivity is too low, so they raise it. Some do the reverse. But, is there really a sensitivity that's wrong? First lets discuss extremes.

Too high of a sensitivity can exist when the mouse begins to skip pixels when moving it from left to right. Obviously, this is a sensitivity that is too high. Too low of a sensitivity is just something ridiculous (100cm/360 for example). I've seen some players use 40cm/360, even 50-60. For simplicity sakes, we'll leave accel out of the discussion (for now).

So, lets take a look at some players. Below I listed some players who are considered top tier (Don't think X player is top tier? Don't discuss it here). I've listed their sensitivities, accel, and what they use to aim (wrist, arm, fingertips, etc). Some are listed with (?) because I'm not 100% sure on that information.

Strenx - Very low sensitivity, wrist + arm
Cooller - Medium sensitivity (Low sensitivity + accel) uses wrist, fingertips, some arm. Aims by flicking the mouse most of the time.
Toxic - Medium sensitivity, wrist, some arm (?)
Stremy - Medium/High sensitivity, some wrist, mostly arm (?)
Rapha - High sensitivity (Med sensitivity + accel), mostly arm.
CZM - High sensitivity, wrist + fingertips (?)

So, first off, are any of these players bad at aiming? Sure, raphas rail might not be amazing, but he makes up for it with his rockets (Side question, is rocket skill affected by sensitivity? Or does it not matter what sensitivity you use, it's purely knowledge of placement of shots). I don't know much about CZM, was he considered a top aimer? Or average with amazing brain (I know he was a very smart player, I just don't know about his aiming).

Each sensitivity has it's flaws. First off, low sensitivity requires more energy to move your mouse, your movement might be not as good as a high sensitivity player, but your hitscan might be very good.

High sensitivity might have worse aiming in regards to rail, but typically higher sens players have excellent rockets and good movement.

Now, LAN. LAN can cause a lot of people to get nervous, shaky, etc. So, this is obviously not a worry for a low sensitivity player, because there is less room for error if your cm/360 is higher. However, a high sensitivity player who has nerve issues typically would suffer more.

Comfort is also key. Some players might not be able to aim using their arm, and just prefer their wrist or fingertips.

Already, we have many factors for a sensitivity. Movement, nerves, how you aim with your hand/wrist/arm, rocket play (subjective), hitscan, and overall, comfort.

So, do you recommend people use a sensitivity like Strenxs? (Low sensitivity) CZMs? (high sensitivity) Raphas? (high sens from accel) Stermys? (Medium/High sensitivity)

Also, do you think any of these sensitivities are ONLY a good scenario for that player? For example, maybe XX player is known for playing with a VERY high sensitivity that no one else that's good can play with. Or, the same situation with a low sensitivity.

Thanks :)
