Which bookshelf speakers to choose: Focal Sopra 1 or B&W 805D3 or KEF Ref 1?

B&W are usually too bright unless you are getting on in years, so it’s not the choice for me (<25). Plus, their dips around the crossover are a no-go for me as well (there is no backing for the “BBC dip”, the LS3/5a has huge off-axis energy, it had nothing to do with flat-ish not being  ideal). 
 
You can’t go wrong between that Focal and that KEF model. If you won’t have a sub, I would just go with the one with deeper bass.

I have only heard the 805D3. I thought it sounded ok but no way would I buy it for the asking price. It was meh for me and sounded like a small speaker that was trying to sound bigger than it was... if that makes sense. 

The bass drew attention to itself with a noticeable bump in the bass but lacked any real depth. I swear I could here port noise too. The highs were good quality but pretty tipped up in B&W fashion. 

Kef is the most laid back of the 3, the B&W is the most tipped up in a smiley face EQ way, and the Focal is slightly hotter than neutral.

My order of preference from my listening tests would be Reference 1 > Sopra 1 > B&W 805D3

What's your room size, near field listening, associated electronics, and type of music? 

I have the KEF Reference 1's in my office. They sit on either end of an 8' long by 42" deep desk and are driven by a Hegel H590. Incredible combination. I'm very satisfied.

I haven't heard the 805 or sopra's.... Owned the Focal 1007 Be bookshelf driven by a mcintosh integrated about a decade ago..... Enjoyable setup but current combo kills it. Good luck!
