Judy, IF there is room to install it, an under-deck autopilot is always going to be more reliable and, pretty much invisible unless you're crawling around the steering post.
The downside is that it is going to cost more and take longer to install. So, if you want "pretty"...be aware that it's gonna cost you, and sell it to your husband on the "better" angle.
Lots of stuff on a machine (and a sailboat is a machine with the real engine spread all over the place) is ugly. Kinda like having a pony, you have to deal with the piles it leaves behind.
