You can set the actuation to require the slightest of pulls to engage a click. It's all fully customizable.

Pressing on the trackpad for click often moves your finger, which moves the cursor during the click. It can get annoying.

You can do that as well, I use that sometimes, but when you press down your finger will move slightly and you might end up clicking somewhere different from where you intended.

That works too but for me it's mentally simpler to pull another finger than having to press with the same one i use to move over the touchpad.
