spürbar vs deutlich
clear / clearly
'deutlich' and 'spürbar' can both express that something is not small or barely noticeable. 'deutlich' is broader: something can be clearly visible, clearly audible, easy to understand, or recognizable in numbers. 'spürbar' fits especially when you feel an effect or notice it in everyday life, for example cold, pressure, tiredness, or a change. When it is about a clear impression in general, 'deutlich' fits. When an effect can be felt or is noticeable, 'spürbar' sounds more natural.
