I think the PRG is a great card for you if you dine out and buy a good amount of plane tickets.

I travel for work once or twice a month to asia from the US and usually buy biz-class tickets. my MR points count has gone up exponentially since switching to this card for buying airfare. (3x on $4000 on average tickets makes for a pretty healthy addition of points on airfare alone).

2x for gas 2x restaurants and 2x for groceries isn't bad either. only bummer about the card is that the gas, groceries and restaurant spend bonuses are valid only in the US. If it was a card that got me bonuses on dining outside the US like the Chase Sapphire or Citi Premier/prestige Id be even more impressed.
