Exploit prices and complexity usually accurately reflect the security of a product when compared to their competitors. Take a look at how much Zerodium pays for full-chain exploits here: https://zerodium.com/program.html
$250,000 - Chrome RCE + SBX (Windows) including a sandbox escape (previously: $150,000)
Whereas it's up to $100k for Edge RCE+SBX, $80k for Firefox RCE+SBX
You obviously need to factor in other things such as how popular the product is compared to competitors, etc., but such a drastic price difference such as this is quite telling.
