It'd depend on the weapons, really. If melee combat I'd totally second the idea of going with plate. If ranged I'd have to go with a modern kevlar body armor like the Interceptor system used by US soldiers, or the 'Dragonskin' armor that's trying to replace it.
And of course, if we're allowed to be
silly I'd just say I'd take one of Mass Effect's 'Hardsuits' - thick, reinforcing armor plates, kevlar-like fibers underneath and topped off with a layer of shields? Yes please.

Plate-armor? Any idea how heavy that is, even if it is spread evenly? How are you going to dodge?
A full suit of plate weighs less than the full gear of a
modern soldier, and is spread evenly (compare to modern soldiers who have to lug that shit mostly on their back) - a knight can most certainly dodge. In fact, he can leap, run, dance, cartwheel, etc. The only real limiters of Plate were that is was
expensive as hell, had to be fitted to the wearer ("generally the size of a dude" is good enough for chain or so - but plate has to fit snuggly) and all that metal and the padding and chain beneath meant you got really hot.
The trope of knights being slow, unwieldy things is wholly incorrect - Plate was used because it was
incredibly effective, not because it made the user slow and easy to kill.
