Before kobe's death? yes. remember media never fully embraced kobe. media rigged kobe his top 5 all time status.
from commercial point of view bron sold more merchandise and shoes than kobe. that's a good indicator on who's more 'popular' because that's a factual evidence. in 2015 when kobe was still in the league bron's shoe generated $340mil. Kobe only did $105mil
LeBron James Tops NBA Shoe Sales at $340 Million for Nike
kobe's popular among hoopers like myself. hoopers respect kobe more than bron IMO cuz the style and grace kobe had. but popularity goes beyond basketball. Bron had broader appeal. and bron's 2010 decision got him to that love/hate status.
kobe also had that love/hate because of kobe was that guy who threatened loyal jordan fan base. also rape allegation 2003 also hurt kobe domestically among women.
in any top athlete ranking i always saw bron ahead of kobe. this was 2016 global ranking by ESPN.
Who's the most famous athlete in the world?
kobe was behind Bron. he was even behind KD.
the whole ranking is a joke, but you get my point. IMO only american athlete who belonged in the world top 10 list was Tiger. IMO Bron or any other american athlete doesn't move the global needle. Yes, china is an anomaly. but china is just 1 country. For ex. nobody knows Kobe in Korea except die hard hoopers.
BUT
Now that Kobe passed away. things are very very different now. Kobe is in the immortal status now.
