I tend to avoid the DSU; feel it's a bit too good for the cost. Using TE recipes... maybe the same deal. I guess I just don't like not being able to see what's in 'em at a glance, where as a good ME Network can do this(and more).
But then again, a Good ME Network is hard to find, most people don't know how to use AE well, as the OP shows. Preformat your disks! Storage Priorities! Sub-network your autocrafting/ore processing!
Plus, I wouldn't play on a "huge server" unless I knew the admins. Not if big tech mods are involved, or if just anyone can do pretty much anything. I have been on servers before where finding a place to live is all but impossible, where all villages on the overworld are ruined and every TC node for miles has been broken or stolen. And where tainted lands run rampant because rookie thaumaturges make huge mistakes.
