Trezor can really protect your bitcoin with ease and you dont have to think always will my bitcoin be hacked by other online as it is an offline storage.
Trezor is a great hardware wallet but it is too expensive. especially for regular users who don't want to spend >$100 for a wallet and keep medium amount of bitcoin there.
i think it is good only if you have a large amount of bitcoin for example for bigger than 100
BTC you should think about getting one.
