The sevices that I use the most, and frankly gives me the best, multi faceted value.
Netflix (have my siblings using the other 4 accounts you get, so we split the cost and cheaper for all of us)
Spotify ( use this daily for workouts, work and driving)
Amazon prime (my own family uses the video service, I use that and prime shipping, sale discounts and other prime benefits)
PSN+ (only buy 12 and 15 month subs when on sale cuts the cost right down. Saved tons through ps+ exclusive sales, play coop games with others, played and completed a LOT PS plus games the last year which saved me a lot of money as well)
I do not have room for much more, in fact with these services I pay for and budgeted for years, it'll be the Disney+ which will the only other service I'll reckon I'll pay for.
Even as someone who is favourable toward playstation, I'll only ever sub to ps now if one of the tiers is linked to ps+. Until then no point.
