That is a strange question.
You imply that the ONLY reason for shaving with a straight razor is to get a BBS shave.
If I wanted a BBS shave I would whip a Gillette Fusion round my face.
Shaving is just another step in my morning ablutions which happens to be made more interesting by the wide variety of tools at my disposal.
BBS doesn't even enter my head.
We used to have a push lawnmower. When he was little, my nephew Stevie used to like to push it. The only thing was, he liked to push it on the sidewalk, because it was easier. Yes, he was having fun ... but he was also missing the point. If he had taken the trouble to learn how to push it on the grass, he might have grown up to be a useful person.
If you think that a Gilette Fusion will give you as good a shave as a straight, then you don't know how to use a straight correctly.
If you like shaving with a straight because it's different, that's fine, go ahead and enjoy yourself. But you're missing the point.
I read a lot of posts by people that say "I can't do this or that because it irritates my skin". It doesn't seem to occur to them that, if it irritates their skin, they may be doing it wrong.
Aesop wrote a fable about a fox who couldn't jump high enough to reach the grapes and finally decided that they were probably sour.
