3TGTE disadvantages:
Its physically bigger than the 4AGE (by quite a large amount!) and therefore heavier.
Parts are getting harder to source, and can be expensive
Stock turbo is far from an engineering masterpiece
Factory computer is a very old analogue fuel only design
Throttle body faces across the top of the motor, making plumbing for an intercooler a bit more difficult
Twin spark distributor makes it a pain in the ass to change to a front mounted throttle body, its bloody huge! 
Cam chain drive system is noisier (and in my opinion less reliable) than the 4AG belt drive. (4AG has a non interference head so if you do bust a belt, no damage will be done)
3TG requires custom engine mounts to be fabricated.
Pistons WILL break if you do not have the engine management tuned perfectly. Detonation kills these engines very fast.
4AGTE/ZE disadvantages:
Difficult to source a strong RWD gearbox
Have to fabricate an exhaust manifold to mount a turbo
4AG advantages: Too many to list. 
I am not biased, I have built and owned both packages in my car. To me the results are clear  We are talking about nearly 10 years difference in engineering between these motors, but dont be discouraged, if you want a 3TGTE, they can be built to run reliably and make good power.
