I'm not the OP, but I'm on the same boat with the OP. For me it's 50/50. The good thing is, when you memorize the commands, and not customize your "base stations" extensively, the difference melts away. My brain works in "contexts". I remember my native keyboard layout and US one, and I operate in one of these contexts. Same for the spoken/written language. When I switch completely, the mental load disappears, however it's not completely free in terms of brainpower. So, removing a context is highly beneficial. When I connect to a remote system, I don't care about the commands, aliases, even the place I'm in. Look to the hostname, remember the task I need to do and let my brain loose on the subject. There are no roadblocks, errors or anything to think about while working. As a result the whole fleet is my home base. I change machines like I change directories. Completely effortless, invisible in fact. Also, extensive aliasing is limiting. When I know the flags to a command, I can compose and flex on the fly, which I do a lot, as the circumstances and needs arise.
