Touch screen is definitely a personal preference. With that being said......
I find touch screen on a lap top useless and cumbersome. Reaching out over the keyboard is not only cumbersome, its ergonomically incorrect and will lead to problems over extended periods. particularly with the lower back.
For a 2 in one or a tablet touchscreen can be great. I have an ASUS android tablet as well as a Microsoft surface pro 4 and use the touch screen on those devices about 50% of the time. All the rest Im using the keyboard and mouse/trackpad. All depends on what Im doing. If it involves using a keyboard at all I'm not using the onscreen version.
