Both the Revels and Kefs have very wide dispersion and great imaging.
I can only speak to the revels and kefs as I have never heard the Legacy speakers.
The Revel 228be is very good technically. It is not far off in sound from the ultima line. Honestly if you never heard them compared could argue they sound the same if that makes sense. I find the brand to not be very engaging myself but can’t really fault the speaker on a technical level. But I could happily own them as their fault less sound would be easy to work with. However I would guess (again never heard the legacy) your legacy have stronger bass and are more interesting.
The only Kef I have heard is the Reference 3. They are not for me. They just lacked dynamics. They had strong bass but seem to rely heavily on the port tuning. Kind of had a one note feel to the bass. I know people love them and will disagree... I thought they sounded good on modern pop music but not much else. A hard pass for me. I demoed them twice with my own music for about an hour each time.
