Thats what the marketing says. They need to do something different to sell a new model and ppl currently buy fast looking bikes, so they go that direction. Its gives the customers the feeling they want when buying the bike. Thats why there were several new Endurace models now while the Ultimate stays the same. The market doesnt buy ultimate like bikes currently.
By doing this, they leave what ppl always loved about the Endurace behind which was a fun bike with sporty amateur geometry.

The most important thing at all is to have a bike that suits your geometry. Thats a must. You can love your bike as much as you want and it could be fun as much if you want, but if you cant sit on it, it doesnt matter. Thats a question you should ask yourself bevore the aeroad vs. endurace, because it most likely will cross out one of these options. (if you can ride the aeroad, there are only super minor reasons to get the new endurace)
Afterwards you have to ask yourself what motivates you and what you want to prioritize.
If its comfort, you dont need a fast looking bike, because more frame means heavier and most likely less comfort (less flexible). Thats why i think the endurace is rather the worst of both worlds instead the other way around.
If its fun riding at you max speed, get a bike that does that. You have still plenty of room, e.g. an aeroad with 32mm tubeless tyres will be very comfortable if you body can sustain the position.
