I think just because of my age and when I started reading comics, Wally is the Flash Im most familiar with. Though I think the most substantial transition I've read regarding these 4 was Bart leaving behind the childish "Impulse" persona and officially becoming Kid Flash. But that again is mostly due to only reading DC Comics on a regular basis for the last 7-8 years.
Over all I love how Wally adds that much needed light heartedness to the big guns of the JLA team. I also enjoy when writers have been creative with the use of his power and how he defeats his rogues gallery. Very cool stuff! The only books I've read recently that focused on the Flash is the Geoff Johns/ Francis Manapul run on the book. Which does have a great combination of showing him use his powers creatively and give you a sense of his character. It's starts with the trade called "The Flash: The Dasterdly Death of the Rogues" You can get it for 40% off at my blog's sponsor INSTOCK TRADES!
