a bit off topic but...
A torque converter automatic is different from a DCT as multiple people have already put it. The key is fluid coupling is used in the torque converter automatic as opposed to a pure mechanical coupling as found in the DCT and manual transmissions. This is also the reason behind torque multiplication.
For this reason, that is why there is traditionally more drivetrain power loss. HOWEVER... this was fixed by the use of a lock up torque converter in which modern day torque converter automatics utilize.
Old school torque converter automatics were hydraulically controlled. That is why there were "Shift Kits" created that basically increased the fluid pressure to cause the transmission to shift harder and firmer. There was a guy under the username keelesdesign that built this for hondas.
Now days... there is advanced sensors and computers that operate solenoids and such that works a LOT better than the old school "slush boxes". With these advancements, the shift time is fast and and each shift is crisp and firm. If you look at the more modern automatic transmissions, you'll find that the "shift kits" that are built for them, often contain stiffer springs and upgraded solenoids for the valve body. There is also clutch packs that are made of different materials. This also affects the firmness of the shifts.
In terms of a DCT, it is essentially 2 manual transmissions placed into 1 transmission housing. You have a clutch for 1,3,5 and a clutch for 2,4,6. When you're in a gear, the next gear is ready to go. (

Now some people say that they don't have fun in an auto because they are missing a clutch pedal, awesome. Keep buying a manual transmission vehicle. It's your car. For others, as was witnessed already, they don't have the ability to heel-toe. They aren't spending all of their time trying focused on cars. Does this make them less of an enthusiast? Definitely not.
There are plenty of reasons that people buy a car with a specific type of transmission. Some need to be the fastest around a track. Some have a disability. Some are tired and exhausted after work and driving a manual in rush hour is a hassle to them.
Some people get the same enjoyment regardless. They are not limited to the fact that they need to have a clutch to enjoy the car. They are still steering the car and that's good enough for them.
All that being said... yes. You should definitely make sure what transmission you want before buying. I saw the same car in a different color and out of curiosity wondered how much to trade for it with 200 miles at the time on my current car and the dealer wanted 4500.
There's no issues with what transmission you pick... but you should definitely make sure before buying. Or have deep pockets to offset that regret...
