Maybe for you personally, but in a general sense I don't see how you can hold a phone and "use both hands" to type individual keys.

One notable advantage of swiping is that you can be quite loose with each single swipe gesture whereas you have to hit the right key many times for each word. That swipe is also usually much quicker than finding multiple keys for most people.

You preferences may reflect youth, eyesight, finger size, co-ordination, phone case usage or other advantages most people don't have.
