Asphalt is a specific kind of bituminous material that together with chipped / crushed rock (or other substrate) is used for "blacktop".
Tar is another word that describe the gooey black component of asphalt.
Really no honest paving contractor would say there is any difference inn these terms.
When it comes to "seal coating" there are different materials that may have components more from the latex / elastomeric range of compounds vs the "oil by product" range...
If you don't want to have to do some kind of maintenance on a fairly regular basis (depends on climate and degree of wear...) you should look at concrete or paver stones instead...
Proper concrete installation is way more than some dude pumping the mix on the ground. There are sidewalks that are 40+ years old near me that are free of visible cracks / shifts because the folks installing them made sure there was adequate site prep -- no nearby tree roots, a nice base of compacted crushed stone to allow for drainage, forms of the proper depth, reinforcing "mesh" to resist slab shifting, skilled finishers that know how to use a "seaming tool" to allow for crack relief...
Concrete is premier surface for driveways and provides the greater longevity with least maintenance, though it is more costly than asphalt...

It's also most appropriate (at most homes) when limited to the parking pad.
The driveway itself, especially when fairly long, should be a rain water permeable surface.
I like the idea of pavers but having seen issues with my parents, I'm less inclined to do so.
Pavers... its an install issue if it didnt work out. the pavers are only as good as the foundation under them.
Idont remember the details, but a normal base is something like 10 inches of crushed concrete. When it gets tamped down (gas powered tamper) it becomes solid. Then I think a thin layer of sand goes in for the pavers to set into.
If done properly, the pavers will be rock steady and as solid as a foot of concrete.
The problem is, too many Do-it-yourselfers think they can go to the local home improvement store, buy some concrete blocks, and throw into a 2 inch cut out in the lawn.

This is not my DIY project. I'll be making the treehouse and other indoor projects this year as well as enjoying my kids this summer.
So I do want to pay for the longest lasting. I'd say a little over half the driveway is flat and the rest is the downslope.
Judging from the comments here, now I'm wondering if I should just so asphalt on the slope and concrete otherwise....
Thanks for all the considerations. I truly appreciate the advice
