which water heater would you recommend for a home with 4 occupants?

We are gonna be moving soon to our new home. The existing water heater is pretty old and turns out we need to replace it immediately. we were wondering if we should get a tankless or a regular one with tank?

which brand would you recommend? Also how much should I budget in for the installation?

is Navien a good brand https://www.navieninc.com/products/npe-240a2? is Homedepot a good place to get a new water heater?
