Hi T1,
I just went through this same conundrum & ended up going the Tabs. Why? :
There factory is close to me & after being taken on a personal tour through the factory with the owner it was obvious the tabs is very well built & they have constantly refined their product on the feedback of owners & are very functional.
Buying direct from the boat maker gave me a sense of comfort if I did have any warranty issues.
The Tabs came standard with some features that were on my must have list including a transom door ect.
Price, for what I wanted they made a premium product for a comparable price of some pressed hull alloy sellers
The formosa is a fantastic boat also & I don’t think you can go wrong with either, I ended up with a 5.5m Tabs Bowrider - & it has been an awesome rig so far. Happy hunting.
