This question has been asked before in many different iterations.
If you're looking to just download from one host i.e. Nitroflare etc, then buy direct from them. Use the affiliate code of your favourite uploader of course.
Multi hosts are for when you want to use different sites to download and/or want additional services i.e streaming torrents through VPN to a raspberry Kodi (Debrids are good for this), or want to be able to download Youtube, Scribd, Vimeo etc etc.
Each multi host offers different services. Hence it's really something you have to trial and error. It's why you should always try the "trial" or smallest package of any multihost and give them a spin, before committing longer term.
You can (of course) free hop/happy hours some, as there are hundreds of multihosters out there. But most don't work or the limits are too small. Maybe we need to have a blog with all these various free and paid multihosters? (hint hint Sanet admins!) There is a subreddit on the subject, too many assholes on Reddit these days, so don't bother with the site.
