I recently bought a Ledger Nano S.
It certainly makes you feel your crypto is more secure.
I will say it has a unique interface that will take a little getting used to, but once you have it's easy. The App interface is easy to use and has many popular coins. The other thing is that I understand they are no longer joint venturing with coins, so unless a coin has the resources to become compatible with the Nano S, you need a 3rd party app interface to get your coins on or off the device. I have Stellar Lumens and rather inconveniently need to use a seperate "account viewer" rather than the ledger app.

However overall it's great and once you get the hang of it very easy to use.
