The problem with choosing a lathe, is it depends on what you are going to make, I started with a second hand Myford Mystro, and now use an Axminster 1628 which allows me to make bigger diameter things, and with the bed extension has the same bed length as the Myford so I can still make fairly long things....
While it is mostly true that you can make small things on a big lathe it is a waste of space if you never use the capacity...
The 2 you have proposed are medium duty medium size lathes and both very capable IF they fit your requirements. The problem with giving advice is we don't know what your requirements are!
My personal opinion is buy a second hand lathe that comes with a chuck and a set of chisels, learn on that and replace bits / add bits as you progress.
My other personal opinion is buy the Record Power DML320, along with the Record Power Chuck, then add a starter set of Robert Sorby Chisels PLUS a set of cheap crappy chisels to learn sharpening on, I guess if you have been knife making you have a sharpening system and some knowledge. Then get a lot of bits of timber and make shavings until you are ready to go get some training.
My sensible advice however remains, go find your local club talk to people, get some training then start buying kit that does what you know you want to do.
