Should I switch jobs if I get a better offer even though I am confortable in my current one?

Do you think you deserve to be paid at that level?

How about just asking for a raise instead? You do have bargaining chips.

Nothing ventured nothing gained.

it will feel good to have higher pay although there will be a few months of adjustment and learning period which might make you feel uncomfortable

but it you get to learn more and also be paid more than why not
