Yes, a hardware bitcoin wallet offers greater security, but you still need to make sure that you are buying a decent device from a reputable source.
You also need to decide how much security you need. For some, having the air gap of a separate wallet is good enough, while others will feel the need to beef up security, and have a device that offers higher levels of security, biometrics, and even isolating the device from possible sources of attack, such as USB chargers.
You also need a backup, just in case. Maybe this is another hardware wallet, or maybe you're going to go for a "cold storage" solution that might include having your private keys printed on paper, or even engraved, stamped, or etched into metal.
Another consideration is price. Unless you're planning to hold huge cryptocurrency investments, then it might sting a bit to spend over $100 on a wallet.
