You can find a complete comparison between the most used frameworks to map when you click here. In this link you can find benchmark comparisons, how to use each framework etc. I decided to use MapStruct because it is easy to use and is so fast.

In light of the Java 8 Stream APIs and with lombok annotation processor library, I am no longer using this mapping frameworks. I create my own mappers by implementing the Converter interface of the spring framework (package org.springframework.core.convert.converter.Converter) 

    @Component
    public class ProductToProductDTO implements Converter<Product, ProductDTO> {
        @Override public ProductDTO convert( Product source ) {
            ProductDTO to = ProductDTO.builder()
                    .name( source.getName())
                    .description( source.getDescription() )
                    .tags(source.getTags().stream().map(t -> t.getTag().getLabel()).collect( Collectors.toList()))
                            .build();
            return to;
        }
    }

    @Builder //lombok annotation to create Builder class
    @Data //lombok annotation to create getters & setters
    @AllArgsConstructor //required for @Builder
    public class ProductDTO  {
        private String name;
        private String description;
        private List<String> tags;
    }

I was in similar situation before while looking for solution to leverage annotation processors. I would go with either Selma or MapStruct. Kinda similar being code generators. Played with both but went with MapStruct. Similar question here in SO can help you - Java mapping: Selma vs MapStruct

Also a project in github that benchmarked object to object mapper frameworks has Selma and MapStruct in the top - https://github.com/arey/java-object-mapper-benchmark
