If your processor is fast, Logistics Pipes is a fun alternative to AE. But keep in mind that LP is very, very hard on the frame rate. I've got an i5 at 4.2 GHz and a Geforce 780, and my (half-LP, half-AE) base drops me to 25 fps. That's without any LP autocrafting - just storage. I recall experiencing severe frame rate issues with it in 1.2.5 as well.
Also, regarding fault tolerance. LP is way, way behind AE in this area. Since LP's crafting depends entirely on interacting with external inventories (logistics crafting tables), an unexpected interruption of a job can leave bits and pieces of it scattered about various tables. If you stack your tables and crafting pipes in a wall-like arrangement to save space, you're going to be clicking on a LOT of tables to find out where the problem lies. Also, LP doesn't seem to have an equivalent to AE's Crafting Monitor. Jobs seem to persist in the network for infinity, even incomplete ones, sometimes stealing a plank here and a stick there long after you forgot about it, and therefore messing up the job you just requested, and every other job you request in the future that requires a stick or a plank. And because you can't view current jobs, you'll have no idea which crafting pipe keeps stealing all of your gosh darned planks unless you request 50 million of them and watch where they go.
Not only that, but again back to the frame rate issue, for every single crafting recipe you want the network to know, you'll need a crafting pipe and a table or machine. Doesn't seem so bad when you stack 40 tables on a wall in a 4x10 arrangement...until you remember that you'll need 1 furnace for every single smelting recipe you use, and a handful of macerators, and a handful of pulverizers...
For the above reasons, my current setup uses LP for all item storing, and AE for all item requesting/crafting. It's a really need combination that works really well, but as I mentioned, I pay for it dearly in frame rate.
