If you want my honest opinion, take the following into account:
1. This is the best rom if you're a gapps user. But if you're gonna use MicroG, I'll recommended using some other rom. Simple reason, you'll find Google apps on every level. Even the dialer, messaging app, clock, all from Google. It's really hard to debloat truly.
2. This rom has reached EOL. The developer has moved to OP7 pro. So don't count on future updates.
I'll suggest using the following roms for a good microG experience :
1. CrDroid - It's very clean and elegant, but there's this annoying call busy issue if you're a volte user.
2. MsM Xtended - Huge amount of customization. Almost too much for some people. But stable.
3. Resurrection Remix - A dev started building RR unofficially quite recently. I'm using this with microG and it looks really great tbh. The dev's pretty cool too. The rom isn't on xda yet, and if you contact me on PM, I'll give you the telegram link of the group.
Hope I could help
