Which Knight goes "well" with this Deatwatch Army?

Greetings honored Knight Pilots,

I am currently building an Deathwatch Army and it will include a freeblade knight as a heavy support/distraction/tank.

However, i cant realy decide on which model ill go with. So i thought ill ask the experts (you)

I will defenetly magnetize him so i can always get all the options but i have been told many diffrent things about which model i should play him as with my army

Heres my Deathwatch List and which knights i prefer so far I have been told i lack tank killing capabilities so i should keep that in mind:

Crusader = good anti tank and fire support, lacks in close range

Errant = good tank, chainsword is always cool, lacks in ranged combat

Preceptor = i have heard people say that canis rex is the "best" knight" but i want to cusomisemy knight heavely so a "named character" isnt going to work, so this would be the closest thing

Warden = good at ranged, good at meele (chainsword is always cool) but lacks anti tank
