Did they also tell you why a body lift over 1" is not so good?
I suspect you're a little confused as to what vehicle we're discussing - you seem to be thinking leaf sprung Samurai (you mention a spring over and a future swap to a 1.6), whilst the OP does not tell us what vehicle, he is posting in the 89~98 Sidekick forum, so presumably that's the vehicle he's asking about.
Anyway - I would challenge your theory that a spring over is easiest - in addition to the welding & fabrication, you're changing the suspension geometry to such an extent that you're going to have to address drive line angles, spring wrap, front end castor angle, and fit some sort of high steer kit to get the tie-rods back to a reasonable angle.
A combination of body & spring lift would be simpler than spring over.
To get back on topic however - for the coil sprung vehicle - assuming the idea is to get increased clearance for a larger tire, a body lift will probably be simpler, provided you don't have the rust issues mentioned in a
Spacers will give you the clearance but will force you to address the suspension geometry changes created by the lift - you're going to have to address shock/strut travel at both ends, and camber change on the front wheels.
