Hastingsontheup I have 3 teens and know that the toddler years were harder.
My third child didn't sleep through until he was three years old (took hour to fall asleep and woke every 90 minutes to, if it was a very good night, 3 hours) due to sensory issues. In the day he had no fear and climbed everything almost compulsively He still has some issues and needs more support (dyslexia, some social issues, nreds a lot of talks especially at bedtime) but he was definitely harder as a toddler. I had five year old and a 3 year old when he was born, so no daytime naps - we were sleep deprived for his whole toddlerhood. Now we sleep at night.
My eldest needs picking up from parties at 2am etc. and all three play football plus one does another sport too - training twice per week for each and a match each a lot of weekends - obviously all on different teams, different locations, different times. We car pool for matches (have to anyway - more kids than parents) and they cycle to training (7km each way for one kid, but he's the one who prefers to cycle even if offered a lift, 4km each way the other two).
Talking happens mostly while doing other things. Obviously they need guidance (relationship, career, school) and guidance around plus the offer of accompanying to medical and dental appointments but not supervision as such.
They also help each other with some things.
They can cook and clean (we all clean together once per week- they didn't like having a cleaner coming into "their" space so they are on board more or less) do laundry and buy their own clothes (with an allowance from us and in one case also part time job money) and obviously can be home alone- one babysits for other people for money and has sole charge of small children so had better be able to!
They cost money in driving lessons and orthodontics (braces) and their allowances and fuel to drive them around and insure them on vehicles as well as obviously food and electricity but their hobbies don't actually cost a fortune and it's good for them to have part time jobs and learn to budget. Its still less than full time childcare for three preschool children (though I didn't work full time when they were all small).
As we've never had family near by we had to pay someone to pick the youngest up from after school care when I went full time as it closed at exactly the time I finished work, and both of us were in non flexible roles back then. With teens they can get themselves home and stay home alone.
