A good SMS app

I am right now using Google Messages, but there are no organization options in it. I can't see personal chats separate from the rest of the sms. I have tried Fossify messages, but it's not perfect. Any SMS app which is feature rich and has great spam support? Edit: SMS Organiser from Microsoft. I of course don't trust it with data, it's Microsoft. But my phone has the option to block internet access entirely for selected apps, so it's offline now. Speaking of features, it has tabs to organise between personal chats, promos, etc.
