Phone suggestion

I'm thinking of buying a phone for myself this summer vacation, but I can't decide, some of my friends say buy iphone, some of my friends say buy andorid, and if you ask me, andorid is better compared to iphone, but if there are people who know here, I want to ask those people, which one do you think would be a better option for me, my current phone is very cramped and I can't process it, and I want to choose the phone considering this.
