I'm a Micro fan - my first new turntable (in 1976) was a Tannoy/Micro TM 44, and for years I used an RX1500 FVG with two MA 505 III arms, and now I'm using a BL 51.
But I question the premise of your question - probably 'the best' was the most expensive, and you can simply look that up. And if buying that 'best' turntable and arm means that you scant the rest of your system, the best will never sound at its best.
The RX 1500 was clearly better than the BL 51, but the difference in my system has been not that obvious - granted, I am using a different arm and cartridge (though not 'better' or 'worse', just different - an SME Series IIIs and high compliance cartridges. I have a good system, but I don't have (or want) a dedicated listening room or an unlimited budget. I suspect that most other listeners are in a similar situation. In audio as in life, it is good to keep in mind that enough is a feast. Your enough may be at a different height than mine, but keep in mind that there is no 'best' - it's contextual, and not just in audio terms - your expenditures of money, time, and attention have to fit with the rest of your life. What used to be known as WAF (wife acceptance factor), and is now DAF (domestic acceptance factor) matters tremendously.
I also question the frequent attribution of Micro Seiki build or design of other arms and tables. There is a German site that claims that Micro made a large number of tables sold under other names, and people frequently claim that Micro made this, that, or the other table or arm, particularly when they are selling the table or arm in question - it might increase the sale price. I have seen little evidence to support all these claims, and just looking at them, it seems to me more likely that other companies such as CEC made some of the low end tables sold under the Micro name (but I will admit I have no concrete evidence of this, either). If Micro was large enough to make or design everything ascribed to them, you would expect that, when they went under, someone would have noticed. But I haven't found much on the web about their demise - they appear to have been incorporated into another small electronic parts company.
I may be wrong, and I'd love to know more.
