For around the price of a Gigabyte Z87X-D3H I would recommend the Gigabyte Z87X-D3H.
In all seriousness even if there was a slightly better board the Gigabyte Z87X-D3H would still win because their RMA hub is in the UK.
Less than a week turnaround should the board break while pushing it.

There's a very strong bias towards gigabyte here. The UK RMA is a bonus of course, but Asus et al make very strong boards too.
