Curious on the reasons you think WA is better than iMessage.
I use Whatsapp to communicate with cross platform users (Android) and for work mostly.
For my private connections I use iMessage, because
- The photos and videos are shared are high quality, uncompressed - Whatsapp is really bad in this even though you select higher quality in settings
- Skeuomorphic design of iMessage is much softer on the eye and easier to use for me.
- WhatsApp being part of Meta is something that makes me switch to iMessage at any chance I get.
- Too many scam/spam messages - this is really annoying.
- Whatsapp calls are buggy, uses too many system resources and Facetime/FT Audio are far superior here.
