Regarding the size of the room... the LRS+ requires a room about 10 x 10+. Their sound is optimized in about a 7’ equilateral triangle with the speakers about 2’ from the rear wall. And, because of the small size and light weight you can move them back and forth out of the way very easily.
Admittedly - that’s not as convenient a bookshelf speakers on a bookshelf or table, but it’s no less convenient than bookshelf speakers on stands.
And... there is absolutely no comparison in the sound quality. Not even close...
