So it's the plumbing phase on my research now. I am limited in space 160 sq ft. I have narrowed it down to these two for hot water heaters:

Tankless/3.7GPM/Size: 17.5"x13.5"x5.5"/Warranty: 7 years against leakage and 2 years parts
https://www.homedepot.com/p/ATMOR-Th...18TP/300164325

Stainless Steel Tanked/Size: 19.5"x19.5"x29"/Warranty: 10 year against leakage and 6 year on parts
https://www.homedepot.com/p/Westingh...0N10/305554770

This is a shower/sink for bathroom, sink in kitchen and a hookup for washer. With a low flow for the shower, sink running and even doing the laundry all at the same time, that tankless will keep up. The 20 gallon should be OK too with no marathon showers happening.
So does it just come down to the size and warranty? Is there any reason not to go tankless? Several people have said parts are harder to get for tankless and in a pinch a tankless part(most likely heat element) is just a quick stop at a home improvement store.
I also see the tanked one has a Uniform Energy Factor of .92 which is high. All the tankless one says is "Save up to 50% on electric bills compared to a traditional tank water heater".

I have allotted for the tanked one to fit in there fine but the tankless one gives me a lot of extra space to work with. So which way to go?

Also just found this: https://www.rinnai.us/faq/tankless-w...s-water-heater
According to that if initial costs are the same and they are for the ones I chose, the tankless is definitely better. The warranty doesn't indicate that though.
It even says in that site that the tankless will outlast the tanked one "almost twice as long in some cases".
