Best credit/Debit cards

Hi guys I’m curious on what is the best credit card in Qatar in terms of rewards and point. Right now my main card is the CB basic credit card (yellow one because I didn’t know which one to get) but now I would want to get a better one because my friends keep on telling me the perks of their credit cards.

Also for reference my salary is 30,000 but it will go up in September (Annual raises happen then) and is there something as a credit score here like there is back in the states
