Handlebar drop & reach matters?

Hello everyone, I’ve decided to replace the handlebar on my road bike. I’ve found two options, similar in shape and dimension but different in reach and drop:

a. reach = 104mm, drop: 127mm

b. reach = 77mm, drop: 119 mm

My question(s) is: will I feel the difference? Is it a ‘day and night‘ difference or more like a ‘mm, this might be better‘ difference?

Im asking this because AI says that B should be better for me (focused more on endurance and long day efforts rather than speed and performance) as it has a more relaxed geometry? do you think it’s right? any type of help/personal experience is appreciated.
