Multiple biases may exist in a convenience sample, some of which may be subtle and unrecognized. There is little opportunity to control for bias in a convenience sample.
Quota provides for more representation than convenience sampling.
Random sampling provides the most representative sample for studies.
Stratified random sampling is a form of probability sampling and provides a representative sample for study.
