One does the same job vertically instead of horizontally, both will be dangerous if not set up correctly.
Both will drill off bonk if not paralleled / squared, both will fall to pieces if not assembled correctly.
I have had the chuck come off my pillar drill after some clown used it as a press and never put it back in properly, that hurt my toe bone init?
Stop talking rubbish and give the lady the advise she asked for.
For my Penneth, the budget bench top drills don't have the quill travel to do the job in one bite.
No issue if you are prepared to mess around or make a jig to counter this.
I replaced mine with a floor standing drill because I wanted the heavier duty, longer travel with hand crank table that I can put my cross slide vice on.
It actually uses a smaller footprint cos it don't need a bench / table to stand on with the benefit of being able to work both sides of it.
Other than that I see no point in spending vast amounts of money on something made in China with the same poor quality and different badge.
