I tried store-brand peanut butter from Whole Foods, Trader Joe's, Costco, and Wegmans. My kids couldn't get enough of the winner.

When I opened the jar of peanut butter from Whole Foods, I immediately noticed there was a ton of oil settled at the top. Although this was the case with almost all the peanut-butter options I tried, the 365 brand seemed to have the most.

I stirred the oil in as best as possible, but the entire jar was still liquidy, with little coagulated lumps of peanut grain mixed in.

In hindsight, this peanut butter also looked a bit odd in its container. I could see that dark peanut matter had settled in layers and wasn't uniformly spread throughout the jar.

This was the first peanut butter I've ever had that I'd call "greasy." It was even too messy for my 6-year-old, who had difficulty spreading it on crackers.

It tasted like an average peanut butter, but its texture threw me off. Whole Foods also stocks other brands of peanut butter, so I'd try one of those before I'd buy this again.

My local Trader Joe's had various peanut-butter options, but I chose the most basic salted, creamy version.

This spread was made with unblanched nuts, which means the peanut skins were left on during processing. It had a darker hue than the other brands of peanut butter I tried, which was appealing to me.

The oil on top of this peanut butter mixed in easily and transformed the spread into a rich, velvety mixture.

It had a good flavor but was a little too salty for me. My kids didn't seem to mind the taste, though they were much more enthusiastic about the winning option.

I'd probably buy it again if I was at Trader Joe's and needed peanut butter.

I was a little overwhelmed by Wegmans' selection, so I went with what I decided to be the most straightforward option: creamy peanut butter. This was the only no-stir peanut butter I tried, so it was also the most convenient and mess-free choice.

Even though this peanut butter had added sugar, the calorie count was on par with the others. It contained 180 calories per 2-tablespoon serving, the same as the Kirkland Signature brand, and a hair less than the 190-calorie 365 and Trader Joe's versions.

Wegmans' peanut butter was tasty and notably denser than the others I tried.

Its texture reminded me of Jif peanut butter because it was thick and a little less creamy than I prefer. Still, it was good, and my kids appreciated its spreadability.

The Kirkland Signature organic creamy peanut butter came in a pack of two 28-ounce containers. This much peanut butter would take a while to consume, so it definitely requires some commitment on the buyer's part.

This peanut butter was creamy, not too salty, and flavorful, with a pleasant touch of graininess. My 6-year-old gave it two thumbs up, and my 3-year-old singled it out for the next day's after-school snack.

It was tasty enough for a sandwich but would work in various recipes due to its unsweetened flavor. My local Costco usually stocks Skippy, but if I ever need an alternative, I'll know the Kirkland Signature brand is a reliable backup.
