In my personal opinion, accelerating uphill compared to my existing bike (Wilier 0SL) is really smooth. On Namsan, since I'm just an average person, there's no significant effect. And with such an extremely light weight, there's definitely a reason for buying something expensive.
Compared to the Wilier 0 SL, the specs are way beyond, but
3-line summary
Slight uphill acceleration is amazing - it really accelerates smoothly
Flat terrain speed feels good
Hills like Namsan are similar by my average person standards
