* Ledger is cheaper when compared to Trezor during the time of my buying.
* Ledger is similar to a pen drive whereas Trezor looks like a mini computing device
* Ledger is really hard due to its stainless style type of design where Trezor is made up of plastic like material.
* Ledger supports vast number of currencies, Trezor has limited number.
* If you are a holder of Ripple, then its of no use buying a Trezor as it doesn't support one which is a big disadvantage when compared to Ledger.
* I feel response rate of Ledger is faster than Trezor when I connect to my offline PC and Ledger has a friendly interface.
* Some like the extra accessories which we receive during the arrival of package of Ledger which is absent in Trezor.
If you are not a holder of Ripple and you don't want your wallet to be stylish and more secure you can go with Trezor.
what this man says is true,
but subjectively (in my opinion and needs) I prefer ledger than trezor
because everyone has different needs
