Terra - Jellico went to Riker, spoke to him man to man without hiding behind his rank. Note that he said he wouldn't order him to fly the shuttle - he asked. He could have ordered and Riker would have obeyed - partly out of his usual sense of duty and partly because his superior officer gave an order.
Jellico didn't treat the crew with respect because they didn't earn it. He took command of the flagship, saw its disgraceful state and went about correcting the issue. He didn't need to listen to Gerodi's objections about improving the engines because Geordi's objections were stupid: "they're adequate according to Starfleet". Adequate might have been enough for Picard but Jellico wanted the flagship in optimal condition, which I can't fault at all - particularly considering the bad relations between the Federation and Cardassians at the time.
His treatment of the Cardassian ambassador was certainly different - but it was calculated. Jellico wasn't particularly violent, but understood how acting like it could work to his advantage in negotiations with Cardassians. Picard would have gone out of his way to remain polite and ignore any jibes the Cardassians made, and the Cardassians would've gotten cocky for it. Jellico put them in their place and remained dominant throughout.
For another example of Picard's arrogance (if "make it so" wasn't enough) look at how he treats Q. Q, a being who could wipe out humanity from time and space so the universe existed as if humanity had never come about, was treated dismally by Picard, who was meant to be representative of humanity. Picard was rude and arrogant - as was Q, of course, but one of the two had the power to exterminate all life in all universes. One of them had every right to be arrogant and hold himself above petty notions of politeness. It wasn't Picard.
