2 stage bottle jacks, any cons?

Like this 12 ton: https://www.amazon.com/dp/B00028FB8Q/?tag=atomicindus08-20 to replace my leaking single stage 12 OTC jack.

No experience with that particular jack but two stage jack will sometimes drop slightly just as thy start to take weight. What happens is the stages will stick slightly as the jack extends and then when the pressure builds they'll unstick and one stage will retract as the other extends. Once they have a load on them they're fine. I'm not sure it's a con, more something to be aware of.
