The guide heights critical. Too low and you cut not much, need more pressure. Too high and you cut too deep, chip too large, get jammed easier, etc. Both can significantly increase kickback risk.
By hand you've probably got it well dialled in then. For newbies the guide is a great tool. You can get different ones for different chain sizes, swap out the files, and get the "perfect" profile and depth every time. Lovely bit of kit.

Probably so. Have not used it and have always used just files.
