I would pick a lever any time of the day, if only the heating time would not be that big. I can play with a timer plug in the morning, but what I do when I come back in the afternoon and need to drink a coffee, waiting 40-60mins for it to heat? Same goes for many machines, not only levers.
The londinium vs Bianca I don't see it equal, as they have totally different BO costs, one is $2800 the other ones is almost $4000. The difference in price is almost a good grinder.
I would consider DE1 vs Londinium if you want, with the plus on the DE1 on heating in 7-10 mins, more compact, posibility to do more things than any other machine (if you are the type, but experiments ask for more coffee to be dumped, so more money down the drain) a good resell value. In my eyes a boxy espresso machine with the old e61 group head design doesn't look good in 2019. It's not even classy, as a lever is.
The + on the Lever machines are the fact that they help you get better results faster. You will not have many problems getting a good shot on a spring lever.
