Thermador vs Miele value

Hi all, I've very recently learned about the magic of steam cooking. I'm about to do a kitchen refresh and was originally going down the path of a double wall oven with a speed oven on top and a convection oven on the bottom. However, after reading too many horror stories on early failures of speed ovens, and also realizing i basically never use an oven, I wanted to find a route where I would make use of what I paid for.

That's where I started looking into a single built-in CSO. The two I've found are highly recommended here and r/Appliance but there are always some unfortunate scenarios.

My problem is that i was originally hoping to keep things around $5k as that was the bosch double oven package that was getting swapped out. The Thermador PODS301B fits it perfectly and is a larger oven at 2.8 cubic feet. And initially, I was thinking of going with a 30x18 Miele 7370. However, since this will be my only oven, I'm having cold feet about going so small (1.7 cubic feet).

That means the next choice would be a Miele 7580, but that adds about $2200 to the price tag just to have enough space if I ever need it. Lowering pre-heat and general performance though because the volume is notably larger.

So I guess, what are all your opinions? Thoughts on these appliances in general. Thermador PODS301B for a large full size steam oven for 5k, Miele 7370 for a small oven for 5k, or a Miele 7580 for a full size oven for 7.2k?

The Miele felt super premium in my local store, it's just a painful pill to swallow when adding it to a relatively pricey (to me) appliance package already. Thank you for any input!
