It's easy to forget that building a concept car or small quantities is dramatically easier than mass producing something that's affordable to the masses.
I own a model 3 and I certainly wasn't dumb enough to pay the 10K for the FSD. That being said I'm not a fan of the other electric cars because the charging infrastructure is garbage. Whenever I stop at a non Tesla charging station I have a very high probability of having to try two or three different plugs before I can get remotely decent current. Electrify America is the network VW was forced to fund after the diesel emission scandal and it's pretty bad. ChargePoint is the other one and they're not very good either.
Definitely don't think the build quality on Tesla's is what it should be and I look forward to the factory in Texas coming out to solve that because Fremont is not going to cut it.
That being said these other cars might be better for the price but good luck charging them.
