I would say "Yes", but I also have two Pinephones and have a Librem 5 order in the queue. One pinephone is my "dev" phone (since mmsd tinkers with core mobile networking stuff, I don't want developing to interfere with my normal usage).
I do not think either the Pinephone nor Librem 5 will have any more significant hardware changes, so the Pinephone/Librem 5 you buy now will be the same one you buy in a year.
If you're unsure, I think buying a Pinephone is a safe bet since its $150 for you to try, and if its not for you, you can probably get your money back by selling it.
What do you want to use it for?
For me, Mobian/Pinephone does everything I need it to do for typical daily usage except for Chatty supporting MMS (and hopefully this will be fixed within a month or so).
