I have written first experiences on that other(unofficial build) thread and you probably didnāt ask from me but I will answer. 
I was really surprised how awesome /e/ OS, even the Blisslauncher. I was thinking that I will another launcher, but I wonāt. Week behind now ans so impressed that I already translated Weather app to my language.
Also already one friend is waiting that I will flash his phone (different phonemodel).
Sure not everything is only positive. For example maincamera has red tint in some lightning conditions, other cameras doesnāt suffer from that, actually picture should have even bit warmer tuning wth other cameras than it does. Also ANXCamera (ported MIUI camera for AOSP devices suffers red tinting at some lightning conditions with every camera. Donāt actusally know what is causing this and can it be fixed.
Can installing AXÅCamera cause issues? Probably not, but very first picture before installing that had yellow tinting. 
Well I did install Magisk in order to install AXNCamera, used Magisk hide and got all my banking applications to work, even NFC payment. But since installing AXNCamera was suggested to do while temporarily removing screenlock, that NFC payment isnāt working anymore, all other bankig apps I got working again. Donāt know would single one of those work without Magisk thought. One more little issue is with Weather Panel, canāt get it to show weather even when following how to. Weather app does work and has all neededpermissions. If I add extra weather widget that will work thought.
Anyway Iām still using this as my dailydriver, hope that this device will get official support and those little issues ie. with camera will get ironed out. I will probably translate apps which are not part of /e/ OS (forked), but are preinstalled to my own language. Nothing against those forked app, but for me it feels like /e/ instance of gitlab is bit more āclosedā, probably isnāt, but I feel like Iām not professional enough to register account there and star translating those forked aps also. 
Well that last part was bit offtopic, but related in the way rhat I definitely recommend to give it a try, Iām already so impressed that I started some translations etc.
Just be aware that itās not perfect yet, has atleast those issues I mentioned.
