Talat talks some sense, as he tries to put across different aspects of an issue and substantiate his arguments on that basis. However, I was surprised with his bias against Karachi. He never talked about budget contraints to Urdu Speaking areas and total discrimination in jobs etc which was the only time he lacked objectivity.
Moeed Pirzada is another good anchor. He discusses issues comprehensively. Leads discussions with short questions and does not interrupt guests unnecessarily. He is polite with good manners. His language skills are good. But, he should be little more energetic.
Najam Sethi is street smart but not objective. He sees world only through his eyes/mind and not objectively. Pragmatism overshadows principles in his case. He seems to be towing agenda of some masters. At times one doubts his sincerity to the country when he talks about our relations with India, USA, ethnic politics, Institutions of Pakistan etc. But overall he is one of the three top anchors.
