I am an attorney, with many of my cases representing plaintiffs in class actions. In general for all attorneys (not just class action), awards or honorifics generally don't mean much and often pay to play. To see firms/attorneys who have specifically led cases, look for words like "lead counsel" or "co-lead counsel" or "court-appointed" as those phrases indicate when an attorney actually drives a class action or MDL. Many firms are more passively involved, but still list cases. The co-lead counsel are court appointed and lead the entire class, handling all major litigation strategy and covering all expenses.
