I had a few smaller levers (hx, open boiler, dipper) and a few normal machines (hx e61, sbdu) and now I have a modified saturated group with a control software module that works like decent, just it allows you to do more, as you can hump in the back of the software and do everything (flow, pressure profiling in one shot, auto, manual, volumetric, control heat by time stamps).
The problem I have with such a complex machine is the need to experiment and try new ideas, so I throw and kill a lot of coffee doing this. If you are the type that experiments a lot, likes to do tests with w/o carrying about throwing expensive coffee then you might consider a DE1.
But if you are the type that drinks coffee and wants a single profile, and sticks to it, do fewer steps, make is simple and easy, don't like to pull 30 coffee in the weekend for the sake of experimenting, then I would say to stick to a lever.
I get better and faster results with a lever machine, than with my "decent" espresso machine. And in general that works for everyone, a lever machine bring faster better results, specially a spring one where you don't have to regulate the flow/pressure by hand.
With a lever all you need to care is puck preparation and lets the machine do the rest. With the decent espresso/pump machines, you need to focus on the profile, understand what changes in the cup if you do a PI at 1 bar or at 3 bar, if you have a PI of 10 sec or a PI of 30 sec (you will always need to adjust grind/profiles on the pump machine).
Heck, even with profiling machines, we all chase to simulate a lever shot, because in the end that gives the best result. The rest is how you put the water in the coffee when doing Preinfusion.
You can see the lever type pressure profiling in the back (blue line) hits 7.5 bar then goes down slowly.
