I am have relative litle experiance in scopes. But I have personally learned to use allot of time on adjusting the focus on a my scopes. When I got new glasses, I went over all of them again. I see in some threads when people are comparing scopes they have looked true all, but have they really adjusted the focus properly when they compared them? As I understand reticle can be unsharp, and parallax adjustement wheel can be off, if not the focus is set properly from the start.
Focus adjustment the most important factor?

Or the scope glass is Just not too good no matter how perfect the parallax adjustment is made they can never be perfectly crystal clear at maximum zoom power. Only certain cheap scopes and crazy expensive scopes will focus crystal clear at max zoom power.
Unfortunately 90-95% under $1200.00 will not based on what I looked through.
If you have relatively bad eyesight you may be very lucky to not see chromatic aberration rainbow effect and blurryness or milkiness at maximum zoom power then just about any scope will look crystal clear to your eyes.
ONE way to know is to go look through a $649 MTC VIPER PRO 5-30x50 zoom past 23x all the way to 30x and if you think thats razor sharp crystal clear then you are lucky everything else mostly all other $500 mid to $1200 scopes will look clear to you.
Or a Sightron SIII 10-50x60 zoom past 32x all the way to 60x see if you think that's crystal clear at 60x. If you think that's clear then be very happy.
Wish I was that lucky.

I focus adjustement (not the magnification adjuster) is meant to be set once, for every user, and should not be needed to adjusted again, until something change with the eyes. I use the recommended method, by looking at the sky, paralax at full range, and full zoom (or the zoom level I will usually be using) and make quick looks thru it, then adjust, until the reticle look the most clearest.

I often adjust the diopter and the side focus, going back and forth on both of them, to tune/achieve the optimal balance of a sharper focus and the least to no parallax error.
There's no concrete rules, it's not like you are breaking the law and risking punishment, lol.. That's just a suggestion in the instructions to use the sky while setting the side focus on infinity and also adjusting the diopter to get the reticle focused.

I adjust the diopter once on a new scope to get the reticle in focus and then forget about it. I use the parrallax adjustment on every target. There are differences in our eyes though, I have tried to use other peoples scopes and could barely make out the reticle, but they thought it was great.
