Amazing post! I personally use the trezor and find it nothing but incredible. The trezor is by far one of my best purchases and it's extremely user friendly. Although the ledger nano S is the most popular external hardware wallet on the market right now, it is backordered for what seems like an eternity. The trezor is an excellent alternative if you're looking to get an external hardware wallet relatively soon. I got mine shipped to my house in less than 2 weeks; however, I did pay the extra expedited shipping cost.
