No way. I don't use iMessage (instead I use Whatsup) but I dont consider Android. I have a Motorola G3 also (work) but the Os is confusing, slow and crash frequently.
Motorola G3 (July 2015, £150 currently on Amazon)
iPhone 6s (September 2015, £497 currently on Amazon)
Obviously a device costing more than 3X as much is going to perform better, eg my S6 (£355, also 2015) almost never crashes and is fast.
Text messages sent per day peaked in 2011 and have declined ever since, we're now half a decade later.
In fact just last month we heard FB and Whatsapp process 60 billion daily messages and growing, SMS 20 billion and dropping. Further, a decent chunk of those SMS messages are from feature phones, i.e. on an iPhone the SMS to IM ratio is more significant than 1:3 and again, growing.
Early on, especially for families, iMessage was somewhat of a big deal. But today and into the future? My whole family is on Whatsapp, from age 10 to age 70 and we all have each others' numbers. We exchange text, videos, voice recording, pictures, there's absolutely zero draw from iMessage. I use SMS exclusively for things like 2FA.
(Tongue in cheek, obviously).
(conclusion: stop blaming the tools and get back to work)
