I haven't driven a Tesla, they don't appeal to me and know they are quick. I did buy a M240i xDrive 2 years ago as a track car and toy and this car is very fast, especially for the money. I'm very happy my wife lets me track it. If she knew how fast this thing is she might veto it too. Also, this vehicle has knobs and buttons, not so on the newer ones. No knobs no buttons no deal. My pickens are getting slim. I hate the big TV screens these vehicles have so distracting.I'm not sold on the electric mowers - but screwed up and drove a Tesla Model Y Performance and OMG that thing is STUPID fast. Like unbelievable and NOTICEABLY faster than the twin turbo V8 BMW X5 I drove a few weeks prior. I was totally sold. My wife however veto'd it for the silly minimalist single screen and that it's "too fast" - she was in it when I put it to the floor (my mistake). For the mowers - I'm like you... just not convinced on new batteries and 5 year replacements. Plus they're getting up there in $$$ and cost as much as the HRN which I think will last 20+ years. I just don't see anyone ever saying they got 20 years out of an EGO.
I do think anyone coming from an HRR would really like the HRN. It's truly a completely different mower at least from the ~2012 HRR that I had and seems to be better in every single way. With that said - you'll probably get a REALLY long time out of that HRR if you take care of it like you are.
I do think the Honda is a better buy than the EGO and getting 20 years out of an EGO, don't think so either. I hope I have another 20+ years. That being said the next mower I buy most likely will be my last. Never know I might have a polluting dinosaur HRR another 20.
