You will always find problems associated with every thing but here’s some recommandations :
For a good start, Signal and his forks (molly…)
For daily basis and better than Signal, choose SimpleX (SimpleX is only feature incomplete for the mainstream app, but in it you can send texts, voices, photos, videos, live messages, have a PP, a alias for your contacts…)
Important stuff and activism, use Briar
Would recommended SimpleX over Signal if you want the “best”, but for users that are pretty new to this maybe Signal
