At FS you'll get great training and pay a TON of money for it too. FS is VERY professional and the lady that handles VA pukes is really nice and very helpful. They also have dedicated ground instructors so the flight instructors do none. One problem: with the CFI shortage all the FS planes look pretty, but they're on the ramp as much as anywhere else. Even the Seminoles.

At Ari-Ben you're basically paying FAR less money and you'll end up with way more multi-engine time. It's not for people who want things done for them. One must be proactive at Ari-Ben. Did I mention way more multi-engine time?

Comes down to what's most important for you. I personally know people at both and they undertand the ups and downs of both.

Best of luck.
