Technically electric ovens are notoriously better for baking. They won’t dry out the food as much and offer more even heating. This is why many chefs use electric ovens. Today many gas ovens come in convection, and the fan will help circulate the air evenly and eliminate hotspots. But I will still say electric overall if you are a big baker.

I would, a dishwasher adds value to a home. They’re so convenient too, especially with large loads and glasses. Washing by hand will get old over time, enjoy the modern conveniences.

Top loaders tend to run like this
Basic no-frill models manual controls $400-$650
Advanced models no agitator electronic controls larger tubs $650-$999

Front-loaders
Base models no steam smaller capacity 3.5-4.0 $649-$799
Steam 4.2 and larger, more advanced cycles and smart controls $800-$1299

That is the average range. I personally have used a front loader for almost 20 years and won’t go back. I feel they wash better and are more convenient to use. When I do the laundry, and that’s rare

To be fair probably nothing anymore.  Sub Zero brand in refrigeration I see people having them 20 years plus but past that maybe a Bluestar range in the cooking.  Most appliances today if you get 10 years you did well.  I will say if you twist my arm for a brand I will push you towards  Whirlpool and or GE.
