Its true that a lot of rotaries can be very versatile but I find that certain ones do better at certain jobs. I thought it might be fun and interesting for us to list our machines and what we use them for primarily. It might inspire us to go outside of our comfort zone with them.
here mine

Gen 7 (soft clip)- black and grey
Gen 4 (hard clip) - lining
Rotary works - lining
German evolution - black and grey
bishop - color / lining (bugpins only)
dan kubin - color packing
Stelth - paper weight (lol)
blunderbuss - waiting to get it in the mail !!!
