Quick Answer
Square is better for in-person retail and service businesses that need a free POS app. PayPal is better as an additional online checkout option where its consumer brand recognition drives conversion.
Head-to-Head Comparison
Square and PayPal both offer flat-rate payment processing accessible to small businesses without long-term contracts. Square is optimized for in-person point-of-sale — with a free POS app, a range of hardware, and tools for retail, restaurants, and service businesses. PayPal is best known as an online checkout button and consumer-to-consumer payment tool, with in-person support through PayPal Zettle. For businesses primarily selling in person, Square's integrated POS ecosystem is more developed. For businesses where consumer-facing PayPal brand recognition matters, PayPal is worth evaluating as an additional checkout option.

Square is generally better for a small retail shop because of its free POS app, integrated inventory management, and broader retail hardware options. PayPal's in-person offering through Zettle is more limited.
You cannot run both on the same physical POS simultaneously, but some businesses use Square for in-person sales and separately offer PayPal as an online checkout option. Whether this makes sense depends on your channel mix and customer expectations.
PayPal is a strong option for online checkout where consumer brand recognition and PayPal wallet payments matter. Square also supports online payments through Square Online. For businesses with significant online sales where checkout conversion is a priority, offering both is a common approach.
PayPal Zettle is PayPal's point-of-sale product for in-person payments, acquired by PayPal in 2018. It offers a card reader and POS app for in-person businesses and is PayPal's primary in-person payment offering.
