I kind of want a new phone as my S9 approaches 2 years old now, but at the same time I am not totally sold on the S20 series.
The stock S20 would seem to have the best form factor for me, but lacks on features compared to the bigger models.
The bigger models seem to have the right features, but are roughly the size of the Note phones, which to me is a bit on the large size.
All of them drop the 3.5mm jack support which is a pain, I currently hook up my phone using this to the car for Spotify, although not itself insurmountable.
I was considering instead opting for an S10 variant, as they still have the 3.5mm jack, and I hope to see some deals on them pop up now the new phones are coming.
Only thing putting me off the S10's is reports I've seen that the camera software is a bit rubbish out of the box, the S9 is reasonable enough for me, but lots of people said the S10 had poor low light performance, and didn't look as good as the Pixels.
