They both got 5 all-star nods, but Chauncey is 3x All-NBA to John’s 1 and 2x All-Def to John’s 1, plus the title, FMVP and a gold with Team USA
But peak for peak I wouldn’t argue against someone saying Wall was better
Basketball Reference puts his HOF probability at 32.4%, slightly above Jermaine O’Neal & Reggie Miller all time which sounds about right
Honestly, yea there's a sneaky strong argument for Chauncey > Wall, depending on what you're looking at.
Wall scored more and got more assists... but he also attempted 50% more shots per game than Billups while shooting much worse (eFG, TS%, etc.,). Had a notably higher usage rate as well. Billups strength was being a very efficient "system pg" that could call a play, then relocate to be a 40% spot-up shooter offball. Obviously Wall was more like Westbrook where bc outside shooting wasn't a strength, he was more optimal with the ball in his hands getting direct assists. And tbh, while direct assists are impressive, they're starting to feel overvalued if not detrimental; esp in cases where that 1 person does everything system takes the place of building a competent offense (i.e. this has been an issue with CP3, Russ, Harden, Luka, even Jokic last year).
With that said tho, other than posting up, Billups couldn't really beat anyone off the dribble... so DET really struggled in late game situations bc none of their guys were dynamic like that. Wall even with his worse 3ball, was still better at scoring inside the 3point line that Chauncey... just a more dynamic, athletic player, albeit a volume scoring pg.
