need to choose last 2 options for UCAS application still

I'm an international year 13 student applying for universities right now and want to pursue computer science.
I'm applying to both the USA and the UK. My top/preferred choice is undoubtedly going to the USA, and that's not in question. so my mindset has been that, if I go to the UK, I want it to be at a top university.
igcses: 9999A*A*A*A*A (mix of edexcel and cie subjects so mix of 9-1 and A*-U system)
as level: AAAA
predicted: A*AAA
My subjects are math, further math, physics and computer science. I'm also doing an EPQ right now.
I'm also certain that I have a very good personal statement and overall application, which is why I want to apply to these top unis.
As I want to go to the USA, all my "safeties" are in the USA. i feel like this is a logical choice cuz, yknow, that's where I really wanna be after all. So I don't want to apply to safety options in the UK.
I've applied to Oxford, Imperial and UCL for computer science so far, I need to fill in the last 2 options/decisions too.
Im considering kings and Warwick, however im not sure as these 2 (along with UCL even tho I alr applied there) have grade requirements just above my predicted. Ive also heard that kings CS is not that great.
Really want to hear any advice or opinions you guys might have for me and where I should send the last 2 applications to.

You don't have to fill in all 5 choices.

Reading your statement you have no intention of going there so why bother applying. Bath and Durham would be great but whether you get in anywhere with 1xA* is questionable.

Opinions on Kings? CS for that matter?
