It is not simple to understand the wording and meaning of your question. First, strain is a status in a body and is not a material property. Next, your problem is not defined so that your question cannot be answered seriously. If you compare e.g. a body under mechanical loads for different materials then larger strains mean softer material (lesser Young's modulus). Why do you talk about effective strain? Do you consider a strain failure criterion? Then you would need the corresponding material data (critical strain). Typically, a softer material allows larger strains.

Dear Ajinkya Ramesh Mane

The material strain is defined as the change in dimensions (based on the original dimensions) as results of applied stress. The material strain is not a material property. You cannot use the strain value to compare your three materials. I suggest that you compare the three materials using the Elastic modulus, Elastic limit, plastic limit, etc. However, the strain value is high because the specimen material exhibits the smallest Elastic modulus classified as soft material.

Thank you

The high strain is only 'bad' if you don't want high strain. It is up to you to decide. For a given force, a lower Young's modulus material will of course have higher strain. If you are concerned about stresses, then you need to evaluate stresses, not strains.
