S25U vs i16 pro vs 17 vs 17 pro ( head talking insta/tiktok reels )

So I'm torn between those 4 phones

Prices :

• iphone 16 pro and iphone 17 and s25U are 850€ .
• iphone 17 pro is 1150€

How I'll use the phone + preferences :

• type of content : educational talking head

• record in cinematic with bokeh blurred background in native camera app + edit on capcut/Inshot then post on TikTok and insta

• I want the best quality possible with minimum compression

• I'll mostly use front camera so I can read with teleprompter while recording video

• I don't care about size and battery life since I have a realme phone with 6,7" and I prefer a smaller phone this time

• Heard that Samsung phones get lot of compression on insta/ tiktok + are more likely to get green line screen issue Is that true ?

Is the 17 pro extra 300$ worth it ?

Those who have both iphone and Samsung or both iphone and iphone Which one gives better video front camera quality ?
