I'll never go back to a manual now, unless it's a track car. Since getting the Jag, I've been converted. Town driving it much less hassle, as is any sort of stop-start traffic. Motorways are better to, as cruise control makes much more sense with an auto. None of this silly suspending cruise because you've changed gear. It just sorts it out. Overtaking is a breeze as well, can concentrate more on the planning of the move and knowing that when I push the pedal, it'll go very fast and I don't have to worry about shifting or missing a gear.
It's very clever with kick down and engine braking. It doesn't wait till you actually floor the accelerator, but measures how far and how fast you are pushing it down. If you push it to the floor reasonably quick, it'll down shift one, if you stamp it down, it'll down shift as far as it can. Likewise on braking, if you're gentle rolling up, it'll not bother down shifting until you're at a stop, but if you stand on the brake, it'll downshift like crazy and use the engine braking to help.
Couple all of this with a sport mode that hangs onto gears till it redlines, and a 'Dynamic' or 'Naughty' button as it's colloquially known, that alters the car from having much softer power delivery, to 'gimme everything now', it's pretty bang on. I've not found a situation yet where I'd use the paddles to put it in a different gear from the one its chosen.
