Ultimate Ears - EVERBOOM

If you like the UE sound and design style, I'd go for a MEGABOOM 4 (maybe an EVERBOOM or EPICBOOM if you want something a little larger). The 360-degree design of the UE speakers is a real benefit IMO. And they all play nicely together in Party mode.

Yesss I’ve had my first one for 10 years, second for 7ish, and they’re stellar. The app is great too

I’m 10 and 7 years on my two booms respectively

Been using the Ultimate Ears Boom for a while now and they’ve been great! Got a second the a bigger one because of how much I liked them.

I'm not sure what exactly you mean by "high quality" - If you are referring to the quality of the speaker itself as well as the sound quality, I would recommend BOOM from ultimate ears (Logitech, Swiss). I've literally thrown it down 2 floors and it survived, the sound quality is by no means bad either.

For the small portable my affections are always with Bose. Some of my favorite speakers for sound stage, portability, and loud reaching well made BT speakers in super portable, easy to handle packages. I have three of their BT speakers and they really perform. As I get less portable, I stumbled into one not on your list — Logitech’s Ultimate Ears brand — which has some smaller BT speakers as well. They’re really well made and they double down on putting resources into the simple features I care about most (sync, app, weatherproofing etc).
