The effect in the front is a lot less. The rear is tied together so you have to adjust both at the same time, effectively. Unless you get chuck's ASP setup that was designed to de-couple that adjustment
for the front I'll mess with camber and not worry too much about toe until I'm done. Then I'll do a cursory check and adjust as needed.
Most important for the front, IMHO, is caster. I just moved my strut tops back 1/8" and WOW what a difference. Still not where I want it, but worlds better than what I had.
If you mess with camber in the front you will most likely be messing with caster at the same time unless you have camber plates installed. Camber plates/boxes allow you to move in a straight slotted grove so you adjust only in one plane at a time. Very nice
