If I had your setup, I would still prefer the client experience of either Infuse, Jellyfin, or Plex, but I don't think I'd value it enough to pay. The first time I used plex, I was impressed by the fact that I didn't really need to do any of what you've described with your collection (for the most part). I just had a huge dump of torrents and other randomly sourced video files, in wildly varying formats, that were named just barely well-enough for Plex to turn that into a very nicely browsable home media experience with no extra work, that I could then stream to any device with a client. Not that I'd be dismissive of manually organizing a collection, it's just not a compelling hobby to me, so a drop in media viewing experience with an amazing frontend that handled all of the meta stuff was spectacular.
In contrast to your HTPC setup, I've actually never even considered owning my own TV, it was just a streamlined way for me to access my collection on other non-TV devices, including the mac I didn't want to keep files on.
