Hi,
I'm another Grob109/Vigilant pilot.
I have no other TMG experience but I can tell you it’s a lovely aircraft. Visibility is excellent and it has good performance. It took me a while to get the hang of it in a cross wind though, taxi and landing
However, compared to the Cessna I fly, I would take the Grob every time.
All the best for your search,
Kind regards,
Buster
