In my experience, sadly, most older machines of nearly any type are better than new. My granny's 1930s waffle maker is still working perfectly and I've been thru 3 in 15 years.
that being said, if you like computerized machines the newest might have features yours doesn't. My aunt still fmq's on her 1901 singer that she inherited, it's been working with nothing but oil and a couple new belts for 115 years now.
