For reliability go with the Acura. Friend of mine had a 2006 TL and it was very powerful and held up quite well. Get ready for immense torque steer though! Best 6spd gearbox in the business too.
While I miss the gear-throws on a Honda, coming from a lifetime of solely driving Japanese, and two decades of solely driving Hondas, I really don't regret finding myself behind the GTI wheel. Perhaps I'll put a short-shift kit on someday, but I can deal with the extra inch.
Perhaps when Honda gets right again, and starts making a respectable hot hatch with rear independent suspension, like they did back in the day, I'll go back to the H-family. Looking at the current crop of CR-Zs and Acura beaks and V6 Venza-wannabe Accords, I ain't holding my breath. Nothing in Honda's stable can compare. Nothing. This ain't 1995 anymore.
Just under 17000 trouble-free miles. If you're like me and are wary about reliability, do what I did and get an extended warranty. Friends don't let friends drive around with Acura-beaks.
