What's your favourite federation starship class?

I like star trek (sorry)
Was bored in the lockdown, and was wondering
What is your favourite federation starship class?
If you designed your own, what would it look like?

Still have a spot for the first one I saw - the Galaxy Class

I'm partial to the smaller Borg Killer ships personally. The Defiant, the Akira and the Prometheus are all favourites.

I've always had a special fondness for the Nova-class - like Voyager it's got the sleekness of the Galaxy-class in a smaller, more techy-looking package that I think makes it a bit more relatable (I love the D, but I feel there's a degree of style over substance to it), but without the Intrepid's shortcomings (IMO), the too-long saucer and stubby little nacelles; instead she's got some inspiration from the Sovereign-class, but without being a show-off about it.

The borg killer style ships are cool as they are not your standard federation geometry.
Intrepid class, but not its variants.
Danube class runabouts, nova class

I like small interesting ships, or absolute juggernaughts
