I started with Logistics pipes and then moved onto AE.
Logistics pipes is very powerful for sorting your inventory, combined with ender chests/pouches you can litterally go caving and never need to go back to your base to unload ore or request new picks/food/torches etc.
Autocrafting is very powerful, especially with satellite pipes, sneaky pipes and so forth. However a large autocrafting farm with logistics pipes will require a LOT of machines. For example if you want to have two things auto crafted in a furnace, you will need two furnaces connected to two separate crafting pipes. The ME Interface of AE though, can use one machine to craft nearly a dozen separate recipes.
In short, Logistics pipes is easier to get into as it doesn't require Nether Quartz, is extremely capable at sorting inventories and can also do a vast amount of auto crafting. However will take up a LOT of room.
AE requires trips to the Nether for Nether quartz, certes quarts/dust is also somewhat rare, but AE can significantly reduce the footprint of your base and.. works very well with Logistics pipes, so youcan start out with LP and introduce AE gradually and run a combination.
My farms are still using logistics pipes, but my inventory is all managed by AE, they work together extremely well!
