Likewise, a Tank getting hit for ~700 HP per hit might need only one cure from either build to top them up, but the SS build would be able to top them up slightly more regularly.
Do they NEED to be topped up more regularly? Depends on how fast the next hit is coming.

A comparison of a WHM BIS SS build compared to a WHM BIS Crit/Det build is actually quite simple:
(1) BIS Crit/Det build (on my char, Seawolf): 513 MND, 436 Crit, 296 Det
Crit Adjusted Healing = 1152.654 HP recovered per Cure
SS is 391, giving a GCD of 2.450s (normal) or 2.077s under Presence of Mind.
(2) BIS SS build (on my char, Seawolf): 513 MND, 388 Crit, 235 Det
Crit Adjusted Healing = 1109.415 HP recovered per Cure
SS is 509, giving a GCD of 2.337s (normal) or 1.853s under Presence of Mind.
Difference in Raw Healing output per Cure: 3.751% in favour of the Crit/Det.
Difference in Cure Casting Speed: 4.588% in favour of the SS build.
This means that a tank can survive taking slightly heavier spikes of damage with the Det/Crit build (each cure landing heals for more), but they can survive taking slightly faster consecutive hits with the SS build (cures land more regularly).
Time until the SS build gets an extra cast: 21 GCDs (51.45 seconds)
This means that a SS build will become able to heal more average HP over time than a Det/Crit build after just under a minute of uninterrupted casting. Unfortunately due to movement mechanics and few on-GCD WHM spells being instantcast, this will not apply to many endgame situations.

TL;DR:
+ SS build will be better than the Crit/Det build after 51.45 seconds of continual on-GCD casting
+ SS build will be be able to land On-GCD abilities 0.1124 seconds sooner after casting than the Crit/Det build (also allows slightly faster dodging).
+ Crit/Det build will return an average of 43.239 more HP per cure than the SS build.
Technically there's also a slight edge to the Crit/Det build in terms of MP consumption (curing for slightly more HP slightly less often will eat less MP!)
It should be noted that SCH's mechanics make Crit stacking a VASTLY more straightforward choice; due to the Adloquium/Enhanced Pet Action bonuses, more regular Instantcast heals, and the fact that SCH has much more "proactive" mitigation such as shields/buffs compared to WHM's "reactive" spike healing.
