Most-used have been:
Olivetti Studio 45
Hermes Media until shifting got tiresome - 99% OCR!
and today, Woodstock 5 - surprisingly llight carriage shift.
Everest K2 carriage shift hurting my hand, otherwise I love it
Lettera 32 (script, brought to write in by mistake)
Studio 44, needs new ribbon
SM9 needs ribbon
Royal Aristocrat mushy margins (the magic has gone)
Remington Deluxe Model 5 gets stuck at center of line
Triumph DeJur heavy feel
Remington Noiseless fun to use but OCR is not up to needs.
here's the Woodstock
and here's a comparison from the Noiseless & the Woodstock, similar numbers of words, about 300 each.
