It's all down to being built for a purpose JB.
Here's two of my bikes.
First one is a hand built, Carbon Cyfac which is designed to get me from A to B as rapidly of possible. It's insanely light, stiff in all the right places (ooh err missus), and the geometry is all about being aero, with good fast handling and climbing capability. Look at the drop from the saddle to the top of the bars to get an idea of the riding position.
I used this bike a lot for big Sportives in the Alps and Pyrenees and it cost close to £10k to put together
The second bike is a Thorn Ripio and is built for long distance touring, on and off road whilst carrying luggage. It's made from steel (for comfort) and has an upright riding position, flat bars which all ow different hand positions, smaller, wider wheels with bigger width tyres, and low range gears for climbing. Again look at the drop to the bars, which is much less so a more relaxed ride.
So there's two extremes to illustrate how cycles, much like motorbikes, can be built for a particular purpose. So decide what you want to do and then buy the bike that's designed to do it
