What ROM do you recommend for Huawei P8 Lite ALE-L21 ?

[derei]

I want to replace the ROM on my Huawei P8 Lite ALE-L21.
Currently installed: Android 5.0.1 ALE-L211C432B190.

Please help me choose a ROM that would be best for this phone (in your opinion), considering:
- Android version newer than 5.0.1
- Supports Dual Sim
- rooted
- Stable (i need a ROM that is not experimental, but suitable for day to day use, something reliable)
- Has no bugs with hardware/software (eg. sensors, or other features)
- doesn't slow the phone significantly

I am aware this type of question often annoys people (as anyone may consider a different ROM as "best"), but if you can leave your personal feelings aside and give your best 2 cents in answering my request would be much appreciated.
Thanks.

I use AOSPA by surdu, this rom have a better battery life than the original emui and it just works fine, I had RROS in the past but AOSPA is more stable

Thanks @BananeMan1
I've got into some trouble with my phone (bootloader became locked after installing the updates to get EMUI 4.1)
I posed the issue here: https://forum.xda-developers.com/p8lite/help/p8lite-ale-l21-unlock-bootloader-t3779631

I have some problems with AOSPA:
- Can't access Phone or SIM contacts, only gmail contacts
- Any imported contacts (VCF) went to gmail account and there is no way to save them in Phone or SIM.
- as is not EMUI, HiSuite doesn't work.

While I'm sure it would be fun to try all ROMs made here, for sure I lack the necessary time, therefore I would like to know which ROM is EMUI and works with HiSuite (if any).

This is Lineage OS 13 for p8 lite. It is unofficial, but it is stable. I currently don't know whether that supports saving contacts to the sim card. But you better have a look at the thread.

There is also an Oreo ROM, which is unstable at the moment and doesn't recommend that.

There is also the Lineage OS 14 for p8 lite 2017.
Yours is 2015 so it won't support neither yours or mine.
