Honestly it depends on your workflow and how your current system is working right now or how you’re planning to implement your workflow into anytype. As @qualquertipo mentions, a new big change in the form of relations as objects and inline sets are coming and it may or may not change how you think about your PKM.
Personally, I’ve successfully integrated my workflow into anytype for about two months now and everything is going great. I’ve revised it a couple of times and none of the bugs mentioned in the community bothered my flow so I wouldn’t worry about that too much 
. Trust me I’ve tried every possibly productivity app out there extensively for about 9 months now and none of them offer the feature suit of Anytype; Actually let me rephrase my sentence 
: I believe only Obsidian and maybe Logseq can give you what Anytype offers you if you’re willing to spend god knows how many hours into creating and customizing a custom CSS theme in order to into turn these apps into a much more desirable and beautiful UI of things such as Anytype or Coda/Notion for that matter; on the other hand many people dig Obsidian’s ultra minimal design so again it’s up to you. But If you don’t want to spend that much time, Anytype is basically without any direct competitor that can match its philosophy and capability.
Regarding sync issues, having anytype on two different devices isn’t necessary for me but nevertheless I didn’t have any major issue so far except one time that I restructured some of my notes while being outside so it hasn’t got the chance to sync the new changes. When I got back online, the 0.29 update was out and I put it to download the update and installed the new update before it had finished syncing and upon booting again all my new restructuring have been gone. I think that’s on me but yeah other than this occasion, I haven’t had any issue with sync.
Hope this helps.
