100%. It's nice to have the typing status, delivered/read status, higher quality of pictures, etc. But I could care less what color it is, and group conversations with SMS/MMS work pretty darn well. I would like a desktop SMS/MMS/iMessage client for my Linux desktop though without having to run a Mac.
What I mean is I'm not constantly fighting to keep messages under a certain size, getting message rejections, weird formatting, or even annoying tapback quotes anymore: basic functionality is all I care about and working fine. Plus I can send funny GIFs back and forth! I have used Telegram, WhatsApp, Discord, etc and they're "nice" and have lots of emotes, but I don't really care too much as long as basic functionality is good.
