I started in second. I don't remember the different XP tables bringing anything to the game. It may function as an attempt to balance the classes over the course of a campaign, but I don't see why that method is actually a good way to do it. As has been mentioned, most campaigns don't last from level 1 to 20. In addition, if each character's balance is considered through each level, the result is that their power is balanced throughout the campaign as well.
If I paid someone to paint my wall purple, and they actually made one side blue, one side red, and put a gradient between the two colors, I would not pay them. I don't see the appeal in one class outshining another class through any innate aspect of the class. Sure, it has to do with taste, but it's also treating each class unfairly, and most people don't like being treated unfairly.
And you are entitled to have opinion. Lots of people share it. My point is some of us found it a great aid to balance. Rapid advancement for the rogue was a big gift that made them more attrsctive to me as a player. On the whole i found 2E a far more balanced game than 3E. And 4E was balanced in a way that just didn't appeal to me. With 2E the classes were balanced by a whole host of things and they still had enough texture and variety to be distinct and interesting.
