I haven't actually ever tried a safer razor. I have wanted to but always feared cutting myself up. Can you shave against the grain with them? I just figured the angle of my jawline and chin would be hard to do since a SR doesn't have the give that my Gillette does. My razor will bow and pivot. If I could get as good a shave as my Gillette with a SR for much cheaper I would definitely switch. That is my only complaint about my Gillette. It costs way too much.glad you found something that works, but i'm curious why you think (or know) that a safety razor would cut the 'crap out of your neck and chin area'?
I'd suggest that any bad experience or fear is related to 1) not having the right combo or razor and blade and 2) poor technique.
Also, as you mentioned, proper prep is everything in terms of the quality of shave.
I have to use a plastic razor when i travel and it's awful. My double edged razor and feather blade leave me smooth as can be (and for roughly ~$.50 per blade IIRC)
