The Ape is a great bike no question and I was seriously considering one myself. I guess the answer to your question is somewhat opinion and personal preferance but some things to consider are reliability, parts availability, comfort depending on what riding you do, anyone local who knows what their doing working on it if you don't do it yourself.
I'd say the Aprilia has come leaps and bounds reliability wise in the last 10 years but still not up to Jap standards. All that said, it's a sweet ride and the motor is great. Sounds like a fantastic deal if it's the same price as a Gen 5. If you like the bike I say go for it.
