Is it worth buying a Ledger?

I'm considering investing in a Ledger hardware wallet to secure my cryptocurrency holdings, but I'm unsure if it's the right decision for me. Can you explain the benefits of using a Ledger and why it might be worth the investment? Are there any drawbacks I should be aware of before making a purchase? Additionally, how does the Ledger compare to other hardware wallets on the market in terms of security, user-friendliness, and cost?
