Rajesh, you'll find either of those 2 acceptable. My personal choice would be the Intrepid from Dollar. I have one rented for later this week in MCI (Kansas City).

I've been using Dollar much more in the past year since I joined their FastLane program. Their prices are good but the service can be spotty in certain locations.

I've been a National Emerald Aisle member for a long time, but have only used them 3-4 times in the past few years due to high prices. My experience is the same as yours...lately National is quite a bit higher for the same class, same location.
