How to choose the best:

Basil

Avoid any stalks that have flowers or buds on them, which could weaken the flavor of the leaves somewhat.

Look for vibrant green color and shiny appearance across the leaves — though some varieties are purple!

Avoid any leaves that look to be turning yellow or brown.

The leaves should feel tender yet robust, and not at all as if they’re soft, wilting, or slimy at all.

Give a good sniff — you’re looking for nice fragrant aroma here. Remember: the main erasing you’re using basil is for just that flavor!

If still on the stalk, you can place them upright in a couple of inches of water, in the fridge, with the jar kept in a plastic bag, but be careful that none of the leaves are below the waterline. You’ll want to change the water every day or two.

Loose basil leaves best in a humid environment, so try wrapping in a moist cloth or paper towel before storing in a plastic bag, and just swap out the cloth at least once per week.
