For me it’s Team Fortress 2. $100 total spent on hats and the Orange Box back in the day, 4200 hours plus of fun, meaning 2.3¢ AUD per hour. Initially I thought DotA2 would be my best but it turns out I’ve spent a lot more money in that game than I thought…
My worst is God of War: Ragnarok. Bought it full price for $95 AUD, only played 2 hours and hated it, meaning $47.50 AUD per hour.
I have to parrot the minecraft claim: ignoring that I’ve bought it for at least 4 friends now and own it on multiple platforms, it’s still easily the one I got the most enjoyment per $ on.
as for least enjoyable? I regretably was an early adopter on Amazons New World. I played it once during the EA period, wasn’t impressed but my morals at that time didn’t allow me to request a refund on it as it felt dirty to buy a preorder then refund it for not liking the game itself. I easily paid 40$ for a game I played a whole 12 minutes of as it didn’t vibe with me, and now due to the servers being shut down at the end of the year, is basically a digital paperweight.
