A La Pavoni? It is going to be more comparable to an Olympia Cremina than anything. The only real difference is that many would argue the Olympia has superior parts with all (as far as I know) being made in-house at Olympia in Switzerland. The pressure-stat on a Cremina is an incredibly simple, unique, well thought out and high quality part that I have never seen on any other machine. All levers are much more reliable pieces of equipment compared to semi-autos due to the minimalistic approach and lack of wiring / electric parts.
A La Pavoni or Cremina are only going to be as consistent as the person who is pulling the shots. The nice part is that if you are inconsistent with your grind / tamp you can pull harder or softer on the lever to adjust the shot flow. Some people like this aspect. I am not a huge fan of it. With a spring-loaded lever I can always push up on the lever if the shot flow is too slow. The spring also adds some form of consistency to the whole process so I have a constant to which I can dial in my grind and tamp. It is all personal preference.
The reason why I eventually got drawn to classic single group commercial levers is that they have the same if not better craftsmanship of an Olympia Cremina, they have larger boilers allowing me to pull shots for as many people as I would like, they steam like banshies and they are pretty hard to come-by depending one the year, make and model so not everyone has one. I am not a fan of plastic within the manufacturing process of anything. It is cheap, fragile and looks horrible in most cases. Almost no pre - 90s commercial lever uses plastic on anything but the portafilter handles, lever knob and steam / water knobs.
One thing that you get with a home lever vs a commercial one is the small portafilter. This is why the La San Marco single group commercial levers have become such a highly prized oddity. They sport the capacity of a commercial machine yet still have a smaller portafilter / basket at 53mm than all other commercial levers which are 58mm. So you get the same capacity and still can get in on some of the more nuanced flavors one can achieve with a smaller diameter / deeper portafilter basket.
Sorry, I got on a role there. That was way more then you asked for
