Do you feel the performance difference between macbook air and pro in a typewriter?

Question

macbook

Good afternoon.
I am faced with the choice of MacBook air 2019 and MacBook pro 13 2018. I tend to air 8/256.
Never used Mac OS before.
The purpose for which a laptop is bought: mail, YouTube, viewing social networks and sites (on average, no more than 2-5 tabs). Work with tables word, excel just a little bit. The simplest photo editing, at the level, take a screenshot and sign. Showing presentations.
Now the questions themselves:
1. Will I notice a difference in performance between air and pro in my cases?
2. Will the operating system UI be equally responsive on both systems?
3. Is there a worthwhile difference between touch pad sizes?
4. Touch bar I don't even know what to ask about this topic...
Hope for detailed answers. In any case, thanks in advance to everyone.

Answer 1

For the purposes set above, there will be no difference, you will work stably for a couple of years

Answer 2

You will hardly notice the difference in performance itself, or rather, it’s just necessary to put 2 models side by side and compare, you won’t notice it at all separately. But do not forget that the Air has PWM (backlight flicker) and still the screen is less pleasant even on the new versions.
And if you take PRO, then only the 13th of 2019 with a touchbar and a 1.4 processor, it is not much more expensive than Air, but 2 times more powerful (including more powerful and PRO version of 2018, also 2 times)
