The Doctor has the sonic screwdriver because it's probally the best Time Lord gadget/tool. It's useful in SO many ways! And, he once had a laser spanner, but Emily Pankhurst stole it, so that's another reason why he has a sonic screwdriver.
The sonic screwdrivers from the second doctor to the tenth doctor were made by the doctor himself but the eleventh doctor's sonic screwdriver was made by the tardis because the tenth doctor's sonic screwdriver wouldnt work.

The doctor's main skill is his intellect, but he is very skilled when using his sonic screwdriver.
Well i have both of them so i can tell you the features: 10th Sonic Screwdriver - Very small and lights up as a torch and has sound. 11th Sonic Screwdriver - It expands, has sound, lights up like a torch, bigger than 10th Sonic Screwdriver. So in my opinion the 11th Sonic Screwdriver but its still up to you as isn't my choice
