The situation in the US is not directly comparable to that in the UK.
Inflation is now at a rate comparable with that in other European countries.
I can't understand why people use sometimes "to", and use "with" the other times..
Is there a difference in meaning?
So..u mean I can use either of them freely?
While some verbs and adjectives colloccate with one, and only one, preposition, some collocate with more than one, with little or no difference in meaning. Dictionaries do not always list all of the things that you may hear. This can be a little confusing for learners. However, the meaning is normally clear from the context when you hear/see a preposition that you don't expect. As far as your own speech/writing is concerned, use the one that you encounter most often.
