I use them daily, so we might just have different priorities.

Bot access is definitely better in Telegram; that’s what I sometimes use it for.

WhatsApp has voice message transcription now, but fortunately I don’t receive many. (I consider it pretty rude to put the effort of messaging on the recipient because the sender can’t be bothered to type or transcribe on their side.)

Everything else you mentioned is a minor inconvenience to me. Knowing the provider can’t mine my message data more than makes up for that.
