I guess foil is more agressive than the rotary?Those shave hair pretty much the way a razor would. I bought a foil that was so aggressive it made me shaves far softer than those I get with a razor. It wasn't good - I got ingrowns like hell.
Use an electric trimmer/clipper: https://www.conair.com/c/24/men39s-grooming/
But razor close is better. Maybe just a razor is good enough then.I think it depends on the quality of the shaver. This was a 200-dollar Braun foil. Previously. I'd tried less-expensive models, and got less-close results.
Try the Norelco One-Blade - that's easy as pie to use, and, well made, it leaves you with stubble. It's not intended for razor-close results.
My electric shaver is very cheap and it worked great. I think I bought it from Walmart or Fred Meyer for less than USD $10 years ago. Something like this.

Some folks are sensitive to foil-type shavers... I use a blade.
Does it skip longer hair? Can I bravely just hit my bio hair with it without being afraid of it shaving the wrong areas? Rotary is better at skipping longer hair maybe?
Rotary is softer.
Doesn't a regular razor blade also skip the long hair, only shave the stubble?Yes, the best aspect about using an electric foil is you can easily shave your stubble while "skipping" your long hair as it doesn't get caught in the foil.
So an electric foil fazor is more foolproof?To an extent, but you can definitely mow down parts you don't want.
