Matter of opinion. I view "Indycar" as a pale shadow of the CART years. Virtually spec series running NASCARE style rules (one car spins in one corner on a 4.5 mile road course and they call a full course yellow? red flag for rain?). Cars that resemble open wheel front end, Canam rear end, and only needing another square foot of metal to be tin tops. None of the current drivers are near the stature of an Andretti, Foyt, Mears, Unser, or Fittipaldi. And consider - thirty years ago the reigning F1 champion came to Indycar and it was seen as a sideways move; an F1 driver, much less the champion, going to "Indycar" today would be considered a step down (probably several steps).
The CART/IRL split also split the sponsor base and fan base, and neither series thrived. When they merged back it was too little too late, it will be at least another generation, if ever, before they achieve their former glory. More likely they will cruise along as a little homegrown alleged open wheel series with only the allure of the Indy 500 to maintain them.
The cars do sound good though.
