I've been using Plex for about 11 years now, going by the date of the receipt for my lifetime payment (that works out to about $7/year, at present, so I'm pretty happy with that deal), and I'd say... not really. On the one hand, it's working great for my use case, and I use it pretty much every single day. But, there are some small issues here and there that just never gets fixed. When I do searches for them I find years old reports that were ignored, so I don't even bother contacting them.
Luckily, for my use case, the issues are mostly tiny cosmetic things. Like how the Android TV client won't show a file is HDR if it only contains DV, not HDR10 as well. The server identifies it correctly, the web client displays it, but not the Android client (to clarify, it plays DV content just fine, it just won't tell you it's a DV file).
