माघे सन्ति त्रयो गुणाः

उपमा कालिदासस्य भारवेरर्थगौरवम्।
दण्डिनः पदलालित्यं माघे सन्ति त्रयो गुणाः॥
upamā kālidāsasya bhāraverarthagauravam |
daṇḍinaḥ padalālityaṁ māghe santi trayo guṇāḥ ||

“Simile is Kalidas’ forte, Bharavi – density of meaning;
Dandi – simplicity and Magha possesses all three qualitites!”

http://www.gaudiyadiscussions.com/index.php?showtopic=1708 gives some outstanding examples of some of these poets and the above verse too (though there is some confusion between दण्डी and नैषध)!
