To me it came down to quality at a price. I have used the cheap stuff, less than $7/sqft, it was terrible, noisy, and didn't stay together. It was professionally installed.I've got most of a first floor to do. Haven't decided to do what you're doing or used the engineered stuff.
IMHO Prefinished or Engineered flooring is terrible at any price.I chose old fashioned nail down stain and finish yourself because ill end up with a better end result for the time and money I had. I've had the new stuff installed in other properties and for the price point I can afford it was terrible.
I cant imagine puzzle piecing the random width stuff together. I am doing 3 1/4" random length and its still challenging to get each run to break right and stagger joints. I find it quickest to layout five or six feet wide swaths the length of the room and then nail them down. It takes an hour or so to pre-plan it and end up with just a few inches of cut at the end of each run.IMHO Prefinished or Engineered flooring is terrible at any price.
SIL whines about her "wood" floor getting wet or the dog scratching it all the time.
Had 2" red oak in the last house. Random width, wide plank pine in this one.
Floors where installed when the house was built in 1978 and refinished in 1995. They still look pretty good but will need "refreshed" in a couple of years
