Thanks all for your help.
I think I wanna proceed with applying for Chase Ink, Chase Ink Preferred, and Amex Plum.
Is it still true that it may help applying at once from different browsers? (I currently have only 1 hard inquiry on my personal account), if not, which of the above 3 - if any is worth trying first?
My total credit utilization is currently at 6% (with the max per card, being one chase card 13%), is it necessary to first pay off my balances for better chances of getting approved?
