Jdownloader2 is a god send when dealing with crappy file hosters.

If you mean general download managers, then IDM hands down. It’s so good that I bought it just to support the devs. Then there’s JDownloader 2 however it’s quite heavy for everyday use. It is a must if you use debrid services though.

Do you mean torrent clients? If so qBittorrent or BiglyBT are very good

Vuze has always been good to me though I don’t know if it is strictly “optimal.”

If you mean direct download: JDownloader2

For torrents: QBittorrent

For usenet: SABnzbd

Xtreme Download Manager

Kget works pretty well for http downloads.
Use Qbittorrent for torrents

I use Internet Download Manager and it has worked like a charm for me. It’s paid, but you can find the pirated version easily!

I tried JDownloader but it didn’t work for me, I’m kind of dumb though so it might have been my fault that it didn’t work in my browser/computer.

IDM, Jdownloader2 and qBittorrent . This should have you covered for pretty much everything. IDM for regular internet browsing and downloading. Jdownloader for debrid links etc (I mainly use it when batch downloading, just simpler/easier for me at least). And then qBittorrent for all your torrenting needs.

I’ve been using Xtreme Download Manager for a long time. It’s lightweight and has a browser extension, so it can easily intercept links. Some websites can’t be easily intercepted by it, so I use JDownloader2 instead for that.

I have been using idm for as long as I can remember.
