Kasun, in my view, there is no "best meter". What is best for me may not be for you, or anyone else.
Some people want a small meter, others want one with Bluetooth (or whatever), some want one with cute software or insulin calculations, and some are concerned to balance some or all of the foregoing with the cost of running the meter - bearing in mind the strips are consumables, and therefore bought many times over, usually.
All meters must perform within internationally recognised tolerances, but all will have rogue reading from time to time - for any number of reasons,
Like all other things in life, perfection just doesn't exist.
