Does you 2 yo play with ball tracks?

I just bought this ball track for my then be about 3yo nephew for Christmas

I love it so much and want for my DS, though I doubt a 21mo is ready to grasp the idea of building it and running balls, but I'd love to introduce him to such toy with something less complicated.
So I'm looking at these:

or

I'm quite torn which one to choose :D.
Does/did your 2yo play with such things? Is there anything else you would suggest?
TIA!

My son got the Haba Kullerbahn for his 1st birthday and at almost 3 he still likes it but it does not get the same amount of love as it used to. We also have the Hape Quadrilla system (older sibling). It requires much more fine motor skill but he is growing into it quickly (and outgrowing the big ball track).

HTH,
