Vastly different kinds of satellites. The KH-11 satellites weigh 17,000 kg, these weight 150kg. KH-11 has 2.4m mirror and resolution of 6cm. The UK ones are resolution of 90cm.
Both kinds are useful, cause the UK ones are small and cheap and good for general surveillance. While the big ones are useful for detail. My feeling is that the US should launch some small ones, but I think they buy that from Planet Labs and others.

Still useful but I wouldn't expect magical resolutions from it. People expect a lot these days because Google maps "satellite view" but the highest zoom levels are generally aerial.
