It’s very close on their quality IMHO. Miles better on the value. I bought a Lumibricks set this year, after decades of buying Lego.

The set design (Cafe) was nice and it makes a good display piece. I liked their build techniques and integrated lights. The individual bricks were clean and with good color uniformity. But after a life of building Lego sets, I was able to quickly tell that tactile forces for connecting pieces were different to Lego. I will buy more of their sets, but I will keep buying Lego too.
