I swap back and forth between SRAM and Shimano regularly and have never missed a shift
I test drove a Scott with Double Tap a few times. I just didn't like it ... the motions are similar, but different enough to feel unnatural after using Tiagra brifters for a couple years. I didn't really understand how the DT worked, and didn't like it at all on the first ride; after I figured things out, I think it's something a person would get used to quickly enough.
Personally, I think what's most important for shifters
on a road bike is ergonomics and comfort. Get whichever feel best in your hands. I think smoothness of shifting has as much to do with the derailleur as the shifters. A sora setup can shift very well if it's adjusted properly and has good cabling, whereas a dura-ace system can shift poorly. But the sora ones are hard to reach from the drops, and have an ergonomic setup most people don't like as much.
If I were the OP's friend, I'd try and answer the question with a couple of test rides.
