There is no best, it varies based on your personal preference.
Why?most people set too high you want low 1-1
Why?
Low DPI means I have to sweep everything off my desk just to turn 90º.
I have a very small control area, so need low sensitivity with a higher DPI.

Some quotes from the thread you linked show lower cpi is more accurate as higher cpi can introduce problems (dependant on sensor)Why?most people set too high you want low 1-1
i use 450

Jitter, or ripple is a hardware error where single units of movement data gathered from the sensor deviate from their "actual" position during tracking, causing the cursor to behave erratically from time to time. This observed behavior occurs as a result of the sensor of the mouse being pushed to its limit. This error when present is usually more pronounced at higher CPI resolutions due to the sensor trying to detect accurate surface data at higher values.
A mouse that produces this error will show noticeable erratic movements
Conclusions
From this example we can see that the estimated useful CPI in this environment is rather small when compared to our sensors maximum capabilities, with even the most outlying resolutions (3840x2400) only peaking at around 3600 CPI in the most lenient of situations. Of course, if we set our CPI within this range of values we will be working at the absolute minimum level of precision, therefore it is not recommended to set our values to satisfy this range as lower CPI steps will net us more precision.
Due to the physical and hardware limitations of the end-user and the mouse, simply adjusting your CPI to its maximum setting, and then adjusting your sensitivity to compensate for your desired distance/360° rotation could lead to a poor tracking environment, or the inability to precisely control your cursor.
In many cases, the closer a sensor tends to reach its maximum CPI, the maximum IPS will drop off more and more due to the hardware being pushed to its maximum capabilities
High dpi is very twitchy and far less accurate.
^ That, pretty much.More dots with the same sensitivity settings = more sensitivity but if you counter the higher DPI with lower in game sensitivity you get much more accurate mouse movement.
TLDR: Higher DPI is better, use higher DPI and then lower ingame sensitivity until its comfortable for you. Only lower the DPI if it still feels too sensitive with ingame sensitivity all the way down.
