Is your carpet and tile a gray color? I ask because I see your only color choices are aluminum or brass. Also, will there be a height difference between carpet and tile?
If I had to choose I'd go with the Schiene since the Reno has a raised/angled edge.

We had a similar problem where travertine met hardwood so we had a transition piece milled locally (couldn't find the correct ht premade) and then had BM custom match a stain to the travertine. Just throwing out other options!

I would talk first to your carpet installer and ask how well they can finish the edges.

Thanks. Our flooring will be dark brown (wood look tile) and cream berber carpet.
I should also add that I use a dyson vacuum as well. Not sure if I should worry about the edge of the carpet at the tile due to the strength of the dyson.

I don't like to see any transition strip between the flooring. Why can't they wrap the carpet?

This is what ours looks like:
