Your first sentence says it best. It is all personal taste.
Like Mark, I prefer the old rose forms (but you already know that). To me the
old rose forms each have their own personal charm. I love the floppy, loose
teas. I see them as graceful and soft. The fully petaled roses, those with
100+ petals are romantic and remind me of a kinder, gentler era and usually are
very fragrant. I also like the simplicity of the single roses. They are the
elegant roses.
I see the "perfect" form of most modern HTs as fake. Only artificial roses
should look like that (or their cousins, the florist roses, that neither smell,
open nor last).

As my mother said to me last night when we were discussing cutting roses for
indoors or leaving them on the bush, "aren't you glad we are able to make that
choice?"

I like choices and the ability to make the choice that suits me. When it comes
to roses, my choice is to leave them on the plant and enjoy the old roses.

It is a matter of personal taste. I love the grace and
form of the classic high-centered hybrid tea rose. It has
beauty and a kind of "restraint" that the big floppy
"antique" and Austin roses do not, and HTs tend to last
longer without looking like garbage, too. On the bush
and in a vase. I only keep roses with poor form (in my
opinion the big floppy ones)because they are so often
fragrant. I am willing to put up with lousy form and
poor substance for fragrance. Speaking of substance, that
is another thing the classic hybrid tea tends to have that the
"old roses" and "nouveau old roses" do not. The petal
thickness tends to be better in hts.

Again--it's all about what you like.
