It is very much worth checking out, yes!
I use it as my daily driver. Some functions, like searching for posts, are abysmally bad - but thankfully that's the only one in that category. For me who can hop over to a Lemmy alt when I need to, PieFed is a great main. Another downside is that often I receive a notification for something that I cannot see, for a variety of reasons including that I've blocked all users from an instance (but hey, on PieFed that's actually possible in the first place!).
PieFed is definitely still in alpha, though ironically a better experience than Lemmy in many ways for all of that, even though a more frustrating one in other ways. An API is currently being tested using the Thunder app, which should help smooth the usability issues.
My advice: most definitely make a PieFed account - you have nothing to lose there - and also hold onto your older one. You'll use it less and less often, you'll see:-). There is a bit of a learning curve though, since PieFed offers so many new features and you'll want to try out this and that to see what works best for you. e.g. for some lower-volume communities, I have notifications set up to receive every single new post, rather than have to wait to find that while scrolling Subscribed or All. It really helps! (But can be quite overwhelming for higher-volume communities - the better way now could be to create a custom topic Feed, which I haven't tried yet but that's awesome that I now can:-).
Yeah the learning curve is real... but fortunately it's bc there is so much more that can be done, not bc like it's "difficult" or anything, just that you get to choose how you want things to be.:-)
Like anything, you get better with practice, so yeah, just start strolling through the posts and enjoy!
PieFed really is the best (most often only) answer that I've seen to SO VERY MANY questions for how to accomplish something on Lemmy (usually you cannot, unless some app provides that feature). Like how to see posts that have nothing whatsoever to do with politics: the topics (often if not always tend to) do that, like Arts & Crafts - and another cool trick is that if you ever do want it, News & Politics is always right there just waiting for you, so there's no longer any need to "subscribe" to those (or maybe subscribe to some of the lower traffic, less contentious communities?), hence you can both have a Subscription feed free of politics (as an example, for someone who wanted that) and still have full access to politics whenever you wanted. It's a whole new way of browsing the Threadiverse, i.e. even if accessing the same Lemmy communities, you approach it all differently - or, you can, if you want.
It's so nice to have choices!:-)
