Dear friend,
I, personally, hate this behavior. If you started looking for a job change, then the prospect of staying at current org is meaningless.
If you have made up a mind then staying is not an option. If you are happy at current org then keep giving interviews is not good especially for your mental health. Constantly comparing current org to other companies which leads to this dilemma. Am i being paid well? Can I get more? Will I get promoted? Work culture there is good?
Having said that, always know your self worth and don't let anyone exploit you. Love your work/profession but your company.
You are with an offer and a good offer. Ask yourself a simple question, why did you start looking for a change - if that criteria is met then go for it.
Prioritisation is a criteria not just for sprint planning. See - P0s must be met, P1s are important but can be traded for, and P2s are good to have.
And whenever someone ask this question with pros and cons. The fact is that you have already made your mind - you just want someone else to give you a green flag.
So whatever is in your head is the right decision
