Alot would depend on how they scale with higher level spell slots. If the first scales by +1d8 per slot and the second scales by 1d6 healing and 1d6 temp hp per slot then i'm choosing it hands down!
Does the rate of scaling matter?
Say you could heal up to 5d8+M as a 5th level spell, but only 4d6 heal/thp (also a 5th level spell)? Which then?
Or 9d8+M as a 9th level spell versus 6d6 heal/thp? Which spell do you prefer?
