B5 A4 2.8 vs. A4 1.8T chipped

[Jason Kohls]

Been poking around the forums and have seen quite an impressive gain
in hp and torque from the various chip manufacturers for the 1.8T:
they seem to bring the numbers in close to the 2.8 for hp and exceed
the torque by a fair margin.  There's also the weight penalty of a 100
pounds or so.
Reliability on the other hand -- with all things maintenance being
equal -- would favor the non-chipped, NA engine, correct? However, the
1.8T, from what I've read, is destined to be a "classic" and I think
it made Edmunds Top-10 engines list, so perhaps this is not the case?

My question is: what would you rather have, power/reliability/gas
mileage -- a B5 A4 2.8 or a chipped B5 A4 1.8T?

I'm looking at getting a "new" daily and have seen quite a few
high-mileage for B5 A4s for dirt cheap.  My priority is reliability
but obviously I'd like some around town pep and some highway passing
and would like to know what the listers think.
