Seedbox providers vary a lot in what they provide whether it be cost, storage, bandwidth, apps and don't expect support beyond the knowledgebase. Like you, I have found that they provide minimum information upfront and you have to try them to see what you get for your money.
However 4 tips -
if you want to seed a torrent you have uploaded then a seedbox makes a humungus difference in (a) speed of seeding first leechers (seconds rather than minutes) and (b) if ratio is important then only with a seedbox will you get any signiifcant share of the data uploaded.
Seedbox providers don't normally count in any bandwidth limitation the data you upload to your seedbox storage or the data you download from your seedbox storage.
If you want to increase download speed from your seedbox don't use ftp instead 'share' your files and use a download program. They can often multiply speeds by 4 to even 10 times. Also you may find time of day makes a big difference that depends on who you are sharing your bandwidth with as managed by your ISP. It may be worth experimenting.
If you want to improve speeds of uploading to your seedbox you will usually find using a Google G Drive helps. Google seems to be able to upload data placed in a G Drive folder very fast. Many seedbox providers (not all) allow you to transfer files directly from other cloud storage - Google and Dropbox are the most common.
Honestly if you use a seedbox with any degree of common sense upload speed and download speed from your ISP will only be an issue if you play online computer games. Seedboxes cost a few dollars a month and are only expensive if you want many TBs of storage. Most people don't really need anything other than very temporary storage. If you really need cloud storage then you should get it from a mainstream provider, don't expect a seedbox provider to be around in the long term.
