I have not heard any Revels lately, but the Focal house sound has always been bright, clear, super detailed, and forward - from experience. These might be alright with the correct amp or cables, though. Not my cup of tea. A bit too detailed for me.
The Vienna Acoustics house sound is much more laid back and to my liking. I heard one of the older floorstanding Vienna's at a show many years ago, and they all seem to have the same house sound. Great midrange and more polite, which for some, might mean too polite. I have the Haydn Jubilee - same house sound. Great timbre with no harshness. Sounds like an original Epos ES-11, but with better highs and bottom end.
As to ease of being driven, I think any of these are easier to drive than Dynaudios(?) Maybe.
