Looking for a DP. I applied for the grandfathered SPG in February 2019 and the Business card in early October 2019. I just received the Chase Boundless card and qualify for the Chase 125K plus 50K certificate.

I just received an upgrade to the Brilliant card with a 100K bonus. If I accept it, would I still get both the Boundless bonus as well as the 100K upgrade bonus? Should I wait for a better upgrade offer? (its the first one I have ever received)
