Personally I really dislike fake grass but I do have it because our garden turns into a quagmire in any amount of rain, due to clay soil and the only other option was a load of gravel instead (one neighbour has got gravel and the other neighbour has opted for fake grass as have a lot of neighbours on our Close (and before anyone automatically starts thinking snobby thoughts, it's a Close full of owned houses that is mostly full of houseproud people, including the few who rent - absolutely hate the assumption that renters don't look after their homes, that is sometimes rife on here.)
Gravel is a no-no for us for a number of reasons - we have dogs and I they hate gravel, I'm disabled and find crossing gravel very difficult and I think large expanses of gravel can look worse than fake grass etc.
We tried bark and we tried it in all sorts of colours but it didn't solve the issues and again, the dogs find it uncomfortable if that's all that's under their paws. We tried having drainage fitted - it didn't work for us or our neighbour.
Fake grass was the last option (as the natural grass we'd tried to care for, for over 10 years was always patchy and turned into a swamp in wet weather (and then there's the horror and guilt I felt when I accidentally cut a frog's front quarter off when I mowed the lawn one Spring when we had failed to do it at the end of Autumn - I still feel guilty now whenever I remember it and I've never mown a lawn since).
We chose fake grass that actually looks like grass, rather than the cheaper carpet-style and it's solved the quagmire issue for both me and my neighbour so my dogs can still go outside without me having to do a huge clean-up and it's easier for me as I can still go out with my crutches as the ground stays firm.
I'm not about to sell my house where we've been happy for over a decade and have almost paid the mortgage off, just because someone who doesn't have an inkling of our circumstances and reasons for choosing fake grass thinks we should move somewhere with a smaller garden!!
I do grow LOTS of flowers and lavender, roses and mint in my garden to help bees and other insects and I feed the local squirrels and birds and hedgehogs - I get a lot of wildlife in my garden and even refused to banish the caterpillars from my rose trees (much to my neighbours horror) and I was delighted when they formed into butterflies and I suddenly had a garden full of butterflies - and although they ate many leaves on the rose tree, the rose tree is fine and always grows back,
