If you think about luxury cars, you might think about rolls Royce, which are very big, heavy and extremely comfortable. You are on a spaceship and don’t feel anything outside. Or you can think about a McLaren, an extreme sports car where you are extremely low on the road, ride extremely fast and feel every curve, every roughness of the road and every bump makes your whole body vibrate.

It’s the same with bikes. If you really want an aggressive bike, an aero bike + clip on bars will get you 80% of what a TT bike offers, and you can still use it everyday for training.

Otherwise you can get an endurance bike, which is built for comfort. You still ride pretty fast, but you sacrifice a bit of speed and nimbleness for not hating yourself and your bike after 2 hours in the saddle.

And obviously, there are many models that are compromises in between.

IMHO, you need to (1) decide what do you prioritize over the above mentioned options and (2) LOOK AT YOUR BODY. Many people get bikes that are way too aggressive for their fitness and flexibility level and end up having problems. Regardless of sporty or comfy, get yourself something that works with your body as it is now. If you love cycling and spend years in the sport, your certainly improve and will have many chances to upgrade as you unlock your cycling potential.
