For solo gigs, I use a Bose L1 1S system with B1 bass module, and a Mackie PROFX8 8-Channel Mixer -- though I only use two of the channels: one for my vocal mic, and one from my pedalboard, into which I've plugged both my 6-string and 12-string acoustics.
Haven't used the compact system or the T1, though I've heard local duo/trio groups use that combination. Seems to work well enough in coffee shop type situations..
I wish I could try a Bose system, but I don't make that kind of dough. lol.
I use an old Taynor AM50 2 channel amp. 60 watts and 2 full proper channels, 1 for the mic and 1 for the acoustic. XLR capable. That's when I actually need my own amp that is. Most of the time, I'm plugging into existing PA systems.
I have used my amp for a gig with up to about 150 people or so. It was in a square-ish venue ( don't know what it was regularly used for, it had bare concrete walls, but carpeting on the on the floor). It was about the same size as your "average" pub mainspace. My amp was good enough for that venue, did quite well actually, but I don't think I'd wanna try to push it for anything much bigger.
Bose is great, but if you're starting out, you don't have to start out with top of the line stuff. There's lots of great 2 channel options out there, and portable PAs that work very nicely.
