So in my experience my local TJ's is actually faster than my local Jewel. My Jewel is understaffed with poorly trained or just unenthusiastic checkers that makes lines move incredibly slow.
However, I really don't get what people buy at TJ's. It seems like a lot of people's primary grocery store which is insane. Yes their selection of pumpkin flavored items is unparalleled, but when it comes to things to compose a meal their selection is limited, often overpriced and their produce quality is incredibly variable. If you are buying meat at TJ's it is very likely you are doing it wrong.
TJ's is great for sniping things. The nuts, the spices (if I don't want to get to an actual spice shop), fresh herbs (so expensive at Jewel), occasionally unique produce etc. But as a general purpose grocery store it is untenable unless you eat nothing but snacks and prepared meals.
