prefinished I am guessing according to your other post.
Square edges
Advantages
floor should be tighter, no where for water/dirt to call home
Disadvantages
You will feel every single height difference, and stub your toes/catch your socks
bevel/micro bevel
Advantages
Regular bevels will be able to hide more height differences so if your subfloor isnt up to par (to a point) it MAY help that
Micro bevels will hade the average allowed height differences 1/16 or so, Floors dont go in flat, thats why you sand them (unfinished)
Disadvantages
Both
Dirt will make a home in these, biger ones will have more.
The floor isnt sealed off so liquid etc that is spilled can get through the bevels and down to sit on the sub floor, which can cause HUGE problems. And you will have lines of the bevels around every board. (I say this because alot of homeowners would tell me about how they had a prefinished floor installed with lines all over the place, They had not realized it was going to look like that)
eased edges
Honestly I havent worked with anything that had that, I would venture to guess that its a cross beween a bevel and no bevel? Until I see a floor installed with it first hand I cant say anything.
