75 gallon or 90 gallon

Not a huge difference, but I like perfecto cause I have one Haha. If you want tangs but your biggest choice is 90 Do a 6 foot 90 with less rock work. That might suffice for a tang possibly

That's gonna be a pretty skinny tank. I'm thinking skip the blue tang until you can squeeze a 180 into your house
The 75/90 can be considered the same for tangs, both are the same footprint. The extra height won't matter either way. There are a few tangs that you could get away with, just do a bit of research on full adult size and aggression.
