Batteries are basically just a commodity. The label on the outside means very little, since there are very few actual battery manufacturers but there are thousands of brand names on labels. There is no such thing as "the Best" battery, and even if there was one that was scientifically tested and found to be superior, that doesn't mean the one you get would live up to the rating. Unfortunately there is a lot of variability in the manufacture of the products.
Shop based on size (so it actually fits the battery box in the bike), CCA (cold cranking amps), reserve capacity, and price. Try to avoid falling for the usual BS in the ads for the various offerings. False and misleading advertising has become the norm these days.
