Hi
I have a pair of Leema Xeros at the end of my sound system for two years and I think they are fantastic, there is anything that I could wish for . So far no plans to replace them
Never heard the Neat Motive 3, so I can't compare them to the Leemas.
The Leema Xero sound dynamic, fast, detailed, refined, got a nice tone and a great tweeter too
I don't have issues with speaker placement or boomy bass. My speakers are placed 24cm away from the rear wall, my living room is small (5x3 sequare metres). I use very heavy speaker stands (40 kg each one
). As a amplifier I use a Rega Brio (the first one) and it is able to drive the Leemas properly, I replaced the speaker jumpers with NAC A5 speaker cable and the sound improved a lot.
Great price here (new)

If you intend to buy the Leemas on second hand you may be lucky an find
some on ebay for less money.
Anyway, I think you should listen to the Leemas and the Motive 3 ( and others) and see which one suit your taste better.
Good luck
