i don't think astro turf looks better. you can clearly tell an astro turf lawn from a real one very quickly and blatantly. it's plastic after all. i get that it's low maintenance which makes it very appealing to a lot of people.
i decided to seed my lawn as IMO grass is better. I am thinking though of sticking astro turf down on top of my decking. decking is just too much maintenance. i'm thinking of painting it to try and stop rot then astro turf over the top. i get that paint will deteriorate every winter but so long as it prevents the rot for longer it's worth it. as just now it looks pretty bad. astro turf over the top of it would make it look nice again plus more appealing to sit down on if need be.
I don't neither but what I am comparing it to is not a top notch lawn that is unblemished. My current lawn is yellow patchy and awful and in that sense it would look better with the added bonus of low maintenance in the future. that's my comparison if it was Wimbledon I wouldn't even think about changing.
