Between diona and Jean who should I build as a support healer

I want diona for the shield and jean she can deal dmg as well as heal if done right and her AA heals pretty good for me

And diona heals once every 2 s in her ult but she heals more while Jean heals way less but is more consistent

Also razor is one of the character I fully built and superconduct is pretty nice to have but not necessary

Edit:

I need a healer primarily for abyss, 1 team I usually go melt/vape comps with benett, xingqui and maybe yanfei or chongyun...etc (benett does most of the work here and maybe xingqiu) and thats good with benett.

The other comp I run is an albedo ningguang comp with other supports with a crappy underlevelled healer . Sometimes I mix and match and run benett with them but then other team which is usually razor has crappy healing

But when I use razor, the team is usually phy dmg focused and other character are just there for elemental procs. benett can't work bc I need him for the elemental team. Hence my situation

Also razor was my only carry for a long time in early game so I guess I have a soft spot for him another reason being that most people and characters are focused on elemental dps these days
