BofA pre-approved me for Alaska Atmos Summit card after denial in September

Bottom line is, I'm unsure of whether to pull the trigger on another attempt at the Atmos Summit with its current 100k bonus.

To add context: Before this year, my credit reports were all mixed up and wrong, which led to a full two weeks of cleaning those up and making sure I wasn't being denied due to verification issues, which happened when I tried to get the Apple Card (of all).

This effort paid off when Capital One approved me for the VentureX just over a month ago, which is my first premium main account and only my second main card, after being an AU on another Venture card.

Before that, I received a denial from BofA last September for the Atmos Summit stating the lack of a relationship with them. Which isn't anything I could help. Citi (who I bank with and have a Custom Cash from) denied me a Strata Premier due to insufficient credit history.

Since then, BofA's added the pre-approval tool which I used to re-check if anything has improved for me.

Lo and behold, I now am pre-approved! I'm just not sure what prompted this, if my improved credit lines did this or they're not considering the lack of a banking relationship I have with them.

I know C1's pretty risk-taking when it comes to approvals, so I didn't have much of a hesitation to pull the trigger for the VX after pre-approval, but with BofA I'm more distrusting.

My credit scores have almost always been 750+, and currently my EQ is 760+, and TU is around the 780-800 mark, and EX was around the same areas as the former.

Thanks!
