ssh -X
Tools shipped with OS-X were pretty and comfortable, but troublesome after upgrades (e.g. laptop Snow Leopard with 10.4/10.5 server).
In any case, cli is just fine, and most importantly, bash and major sysutils haven't *changed* rigorously over 10 years.
With Gui utils, it's always the latest trend in UI whizzbang that takes up worthless time trying to figure out whether this simple and
once in a year task is actually accomplished by pressing a newfangled button with ribbonized toolbars and tooltips in the newer version of the same app.
I like to spend my time learning on interesting subjects without throwing away experience uselessly.
