I use both. The bottle jack is nice for getting under the rig when you just need a few inches to get something under a stuck tire. The stock bottle jack barely lifts my truck enough to get a 31" mud terrian tire off the ground. Would not work in mud, only flat pavement. Might consider getting one out of a full sized truck at the wrecking yard.

I also use a high lift but it requires a short chain or strap to wrap around the bottom of the tire for getting unstuck. I also use the ARB bumper and draw tite hitch for lifting the front and rear. Hi-lift jacks do not fit stock Toyotas well, you need an anchor point. The High Lift wheel hooks will not fit into the slots on Aluminum Toyota wheels.
