Samsung to iPhone?

hello, everyone! since 2015, i've had a samsung note, but as i update my phone every three to five years, i've been considering moving to an iphone next year (2024). i just want to try something different hehe. at the moment, i have a note 10 plus, galaxy buds, and an hp spectre (windows)

i wanted to hear your thoughts, so which one do you think is better? which is more cost-effective?

(a) purchase the most recent iphone model; keep my note 10 plus

(b) purchase the most recent iphone model; upgrade my note 10 plus to the most recent samsung note model

(c) purchase the most recent samsung note model; switch from my note 10 plus to an older iphone model (as i'm new to the ecosystem).

tia!
