Yup!!! The Speedo Solar is definitely my first choice. Also, I've really been liking the mini brief from Little Rok lately. Its cut very similar to the solar, it just feels much lighter (?). I've got three of them that I've been wearing

Finally, a fellow European at least! :P
I agree, it does appear to be made into a much bigger deal in USA at least from what I see.

Stocky, what is your basis? Just curious.

Georgia USA
 

I live in North Georgia in the US. Every once in a while a swim brief is seen, but way too many board shorts.

My basis? :)

Kent, England
 

I'm in Kent the Garden of England.
It's ok to wear 11" side shorts in the street and shops. In the public swimming pools I wear 2" side briefs including orange Aussiebums without comment as do others for lane swimming. Recently had a chat with an older guy (and his wife) he was also wearing brightly coloured 2" swim briefs and said he wears a thong in the garden when he can. The younger fast swimmers tend to wear jammers. Those that wear long baggy board shorts in the lane sessions tend to get left behind and either get something briefer for the next time or stay in the public play sessions.
Kent has sea on 3 sides, the Thames Estuary to the North and the English Channel to the East and South. We have naturist beaches on all 3 coasts. I was at Folkestone Warren beach on Sunday and could see France on the horizon. To reach the beach there is a long walk along the sea defences, saw a couple of guys in Speedos on the first beach and once the crowds thinned out I stripped down to my ice blue 1.5" Aussiebums, remembering not to get them wet.
In conclusion speedos are rare in Kent but you can wear them without issue in the pools and on the beaches, short shorts are accepted, average shorts length is dropping but still too many ugly long shorts about.

USA here, in the (allegedly) great state of Ohio. Wear briefs or smaller everywhere. As the nick suggests, thongs whenever possible. Never had a problem in briefs, and rarely in thongs, despite Ohio's generally conservative reputation. That said, I almost never see other guys wearing them while I'm out. Only when I have been on vacation in Florida have they been even remotely common.

USA, up in the PNW, in a state called Washington, in a city called Tacoma.

It's cold most of the time, but I manage to wear my spandex swim briefs throughout the year as my favorite undies.

I am in New Mexico. I have brick wall around my backyard area and it allows me to hang out in my speedos in the privacy of my home and get some sun. Only wish I had a pool.

Scotland for me. Same here as rest of UK I guess. Traditional swim shorts, board shorts and occasional speedos. My preference is the kiniki range of micro swim bikinis of which I have the full set of solid colours and wear them at times. No issues so far😊
