I had both but weather in MO is alot different than CA, and you probably wouldn't need a hardtop. I see people driving around in the summer with the hardtop on and wonder why even have a Jeep?
The good thing about hardtops are they are a little more protection and warmth in the winter, again probably not needed in your area. If you get snow, you can scrape the windows on a hardtop and wouldn't want to do that on a softtop. You can secure your vehicle better with a hardtop and hard doors than just a softtop.
The bad is they are bulky and heavy. I can lift mine on and off on my own, but its not a real smart thing to do. They take up alot of room in a garage unless you can store them outside which I can't do in my neighborhood. You can always build a storage dolly and store it vertically which is nice.
When I sold mine, I thought that I would never buy another hardtop but I found one really cheap. Its nice to have the choice between either a softtop or hardtop so it just comes down to do you really need one for your climate, can you find one for a good price, and can you store it out of the way when its off.
