Someone correct me if I'm wrong, but that means for about the same price after credit, the MrCool seems like the much better option!

Mine was Pioneer version. My line set was not pre-charged ( condenser was ) so I knew I would need a vacuum pump. Arrived as a kit. I ran my own 220 wiring and disconnect. I had to purchase a whip separately to connect wiring the disconnect to the condenser.
It is quite literally plug and play. However it requires an electrical outlet ( new or existing ).
My line set was sized incorrectly - whoever pulled the order didn't verify - so I chose to purchase my own copper and cut to length. It also meant I had to flare my own end.
Had the correct line set arrived: this would be very simple.
FWIW: I used nitrogen to help clear any water/humidity out of the line set.
I ran the vacuum pump for 35-40 minutes. Then let it sit for a few hours to verify no leaks.
I need two units. Downstairs I need a 18k. I think I'm going to get the Senville Aura as it has a shorter run of line and works to heat at much lower temps. I could get the Mr. Cool unit, cut and re-flare the pipe but that defeats the purpose of the pre-charged lines. For my master suite the Mr. Cool 12k will be perfect. I've watched a ton of videos and this seems easily DIY to me, including wiring.
I wish manufacturers would publish HSPF vs. ambient temperature. Usually it's around 3-5 but the colder ambient (outside) is, the lower the factor since it's "more difficult" to extract heat from colder air and move it inside.
I have 3 heating options (some cases 4) in my home and I know the cost of the input very well (NG, electricity, propane, wood pellets), but choosing which to use is difficult (meaning what's cheapest to run). The largest wild card is that I know my (air source) heat pumps have reduced efficiencies (HSPF) at colder temps, but what exactly is the interplay?
Right now, I have central ac but it doesn't cool my upstairs, downstairs still to an extent - so was thinking of making it 2 zones.
PS: I will need to run 4 dedicated lines from my main panel to these for sure, and will need to hire an electrician!
If you require Heat, get a Heat Pump Unit.
The house will be much more comfortable.
And will cost you pretty much the same.

Your best option is to look up the COP of the system at different operating temperatures. You can find this at a ashp.neep.org. they have a vast database of all modern heat pumps, along with their output curve for different temps.
Lastly, there are calculators people have made that help you know when it's more cost effective to run NG or your heat pump. Check out r/heatpumps subreddit for that stuff. One of the more useful calculators for that is here: https://siecje.qithub.i
