CUBE Agree C:62 Pro blackline or Cube Attain C:62 SLT

Hey! Im looking at a new bike to go on mostly short rides, 20-50 km, but sometimes also 100-150 ish.
The one store near me has the CUBE Agree C:62 Pro in stock, but the attain in said to maybe come in a month....Which one should i go for? Is the attain much more comfortable for a new-ish rider than the agree? The price difference is not very big here. I can also only choose 53 cm. My dimensions are 179 cm height and 79-80 inside leg measurement.
