Use Peertube if one of your concern is to promote a world where YouTube is not the only way for a creator to host videos. It shows them (and sponsors) that the efforts to maintain another platform is viable. Resources are not the main issue for Peertube, as it uses WebTorrent to distribute a video using peer-to-peer.
If you fear to miss something in the YouTube comments (really?), use Invidious.
It mostly depends where. French use it for almost anything, even more since COVID. On the other hand, Germans have a tradition to prefer cash.
