well in all honesty the only ones of my vintage machines I have actually sewn on is my 301, FW, and my oldest treadle, the 1873 Domestic. The others are in my studio waiting on it to be done and cleared out so they can be put into useful places instead of huddled in a mass in one corner. Maybe I'm a traitor to admit it but right now nearly 100% of my sewing is done on my new Viking Ruby because its set up temporarily in the corner of my bedroom. I still resort to my Bernina 1260 for uniforms though because I have the easiest time doing FM with it- a handy trait when sewing on all those weird shaped military patches and ranks.
