Not OP but I'll chime in.
I have a range of devices myself and within in my social circle. I also live abroad from my family so good communication is key.
My work phone is an iPhone, my personal an Android, and across the family there is a multitude of old and new, Android and Apple.
Telegram is using (or used) some homebrew encryption protocol and I simply don't trust it. As it doesn't have a proper tried and tested encryption I'm not going to use it. (The encryption may have changed by now, as I haven't kept tabs on it.)
Signal is okay. There are 2 main things that irk me. Signal's Windows App is bad. Long loading times, bad UI. Keeps crashing for me. I also frequently video chat with family. Signal's quality is considerably worse than that of other services. The sound is choppy and video may or may not work. This is on all devices I own, regardless of network speed.
iMessage and FaceTime are good but platform locked. The video call quality on FaceTime is the best one across all services for me. The picture and sound is just significantly clearer than anywhere else. If I talk to family members with an Apple device I will generally use FaceTime.
WhatsApp still remains my main one for the simple reason that it gives me the best average experience across all devices and circumstances. Video and phone calls could be better but are acceptable. Chats are easy to use and work. Service quality is generally good. WhatsApp for me stands out because it doesn't really negatively stand out anywhere else. Yes, owned by Facebook is something I'm not entirely comfortable with, but right now, there simply isn't any other application that for me is consistently average across every platform.
