Gravel is a pain in the arse because:
It gets full of weeds no matter how hard you work - it is not low maintenance. You have to weed it and rake it, and getting layers of wet autumn leaves off it is not easy.
Cats like to use it as a litter tray, and children like flinging fistfuls of it.
Rolling your wheelie bin or pushing a bike/buggy/wheelchair across gravel is a nightmare.
Walking across gravel in high heels is quite tricky.
The stuff gets dragged out into the road so you are forever losing it and having to sweep it up.
Unless it has been properly graded using the right size of hardcore and then compacted gravel on top by contractors who really know what they are doing, it goes all lumpy and you get tracks in it.
Done properly, it is not as cheap as you'd expect.
If you are going to decide on that option, then at least have a solid path for foot traffic to your front door and only have the gravel from the roadside to you garage doors.
