I have never used /e/ but I do not have a positive impression of it. From what I can tell it's just LineageOS but with microG (with Google registration turned on by default) and some "app store" thing (which tells you what proprietary applications are "good"), tied to their cloud (it's okay because it's not Google you see) and with a proprietary map app with a "good privacy policy."
Privacy policies are not a substitute for free software licenses and any organization suggesting they are is not reputable in my opinion.
