Best Firmware/Rom for Mk808b plus clones

[techlover7]

Hi ,
Please can you suggest the best firmware/rom to use on my Mk808b plus (BoSuntop brand) purchased from aliexpress?
I heard different wifi chips are being used for this model so flashing any firmware without knowing the wifi chip can cause wifi & bluetooth problems.
Is there a rom which would work fine with all the models ?

Open the pen and read the wifi module name from the chip..then you will know which rom you can install
