Autoland would definitely be preferable, a CAT III ILS would be ideal although you can still autoland off a CAT I beam. CAT IIIs tend to be limited to big airports due to cost and restrictions on the surrounding terrain and obstacles.

With autoland though, it's not just a simple button push. The aircraft needs to be descended around any terrain, navigated through any weather, and put into the landing configuration. If it'll be landing somewhere other than the planned destination, there's also a fair amount of reprogramming of the FMS.
