EGO Mowers 2025

Looking to upgrade my 2135SP to either the 2206, 2236, 2244 or even the commercial 5300 this spring. Seems like most of these must have hit the market late 2024 as the reviews are sparse. All information seems pretty vague as to the whine of the self propel motor (and even dependent on manufacture date), advantages of the Peak Power/dual battery system, aluminum vs composite deck, and so on.

Any idea as to when we'll reach a critical mass of reviews to guide that decision or whether I should just pull the trigger? Prefer quality of cut over battery life and not too concerned about cost. Have (2) 7.5's that still have close to original life from 3-5 years ago. It's hard for me to tell from what I've read about how big of a nuisance the whine issue is, and whether all the new mowers have solved that problem.
