Looking for Advice About an Unused Checking Account

I opened a second checking account with Capital One to be my "expense account" because it was quick and free to do online. I use my Iberiabank checking and savings for everything else.

I've since realized their website is absolute trash and I went into a Chase branch and opened a checking with them to use instead (way better, I know). If I've transferred all of my funds out of that Capital One account...is there any negatives or positives in closing/keeping that account?

Will it affect my credit score by closing it? It's only been open 3-4 months.
