G'day mate
Welcome.
I don't think you could go wrong with any of the brands you have mentioned.
I looked at Wild Boar when I bought my F/F a year or so ago.
I was hugely impressed with them. Great finish. QC seemed super high. He was genuinely proud of his product.
I have heard nothing bad about Stoney Creek. A few people on a F/F site have them and no complaints I can think of.
Modcon are reputable too. You couldn't go wrong.
They are all a little bit different.. Storage/ fridge box size. Fitting etc.
I would guess they all do a boat loader?
Some will have quick awnings as well as standard. Etc
Best would be to try to pick one your current stuff fits in...
Nothing worse than getting the camper and finding your fridge doesn't fit.
lol
Check their specs. See what suits you and your style of camping and equipment.
Then buy that one.
Then.. Check it carefully before driving away.
Good luck with your search.
