The 1200xl is basically a 2080 with a slight change of the pump assembly, the new parts fit the old pump, different colour, possibly a slightly different material
I purchased a pro5e about 18 months ago, not sure I would purchase another, too much faff to set it up, the flow monitor/when it needs cleaning feature is (in my experience) a waste of time
The adjustable flow is great, the dc motor is more noisy than the motor in a classic, the filter itself works well, but is crazy expensive for what it is, I don’t really need to see how it’s working on my phone/pc, I can see whether it need cleaning by checking the flow from the return
My ideal (smallish) Eheim would be a classic with an extra 50mm on top containing a pre filter
I can’t complain about the 1200xl/2080 never had a problem, I have had a 2080 for many years, and apart from cleaning (i did once remove scale build up on the tap/valve assembly, the flow meter no longer works), replacing serviceable parts, haven’t had to touch it
