nightcraw1er.488: 1) not quite a full client, only the download part. A client can do other things like achievements, online saves etc. Downloader was a smaller simpler app.
Well, it is a client. Client is like being pregnant or dead, it either is or isn't. There is no middle-ground. If you are both pregnant and dead, that is a double-whammy.
Of the three (web browser, GOG Downloader and Galaxy), using the GOG Downloader was and is actually the most illogical.
With a web browser and Galaxy you have to log in only once, with either of those. You also initiate the downloads straight from that client (a web browser or Galaxy).
With GOG Downloader, you have to log in twice to your account (with your web browser, AND the GOG Downloader client), and run the two clients side by side. Then you initiate the download from your web browser, but it gets started on the GOG Downloader client instead.
I still recall when I tried the GOG Downloader the first time. I even asked here how am I supposed to use it, as all I got after running it and logging into it an empty screen. Only later I realized that was not enough, I was supposed to log in to my account also with my web browser. Errr, ok I guess, normal for people who are used to using e.g. bittorrent clients I guess... I was always more of an Emule guy anyway, Emule didn't necessarily need web browsers or web pages to initiate downloads but you could search for files and start their downloads also from within the Emule application.
rjbuffchix: 1. While I guess you could say Downloader is "technically" a client in a software sense, that misses the context of how people actually talk and use the term in practice. Those of us who are anti-Galaxy and pro-Downloader would consider Downloader to be "a download manager" more than a "client".
Download managers (for web browsers) don't require you to log into an online account with them. GOG Downloader does. That is one of the reasons it is a client and not a "mere download manager".
You can say Galaxy is a heavier client with lots of extra features that are unnecessary for someone who just wants to download standalone offline installers with it, but that doesn't make GOG Downloader a "non-client". It is simply a lighter client more concentrated to one purpose (downloading of the offline installers and extras), that's all.
