"DIY" vs Non-"DIY" Mini splits (lemmy.world)

Is there significant quality differences between DIY mini splits (Mr. Cool, Pioneer) and non-DIY mini splits (Mitsubishi, Daikin)?

I'm going to replace 4 window and portable AC units with something more permanent, because 2 are under-powered and only one provides heat. Thinking of installing 4 single-zone systems because only 1-2 would need to be on at the same time, and it would simplify installation a bit.

I will be diy-ing regardless, so I would prefer not needing to buy extra tools and refrigerant from shady suppliers. But, if non-DIY systems are significantly better, that's a trade-off I'm willing to make.

I was able to buy some R-410a on eBay when I installed mine a couple years ago. Looking again, I don't see any more listed.

The tools weren't too expensive. I wasn't able to buy lineset covers locally, and I'm sure I paid a little premium buying them online.

I wasn't able to do a high pressure leak test because I was only able to get a low pressure nitrogen regulator. I ended up tearing my hair out for months because the system barely worked because there was a leak I didn't find until I noticed oil on a fitting.

Having a recovery pump and cylinder would be invaluable for troubleshooting leaks. But they're so expensive.
