I see a lot of posts saying how good TE3 is, and personally it seems no better than any other mod. What's so good about it?)

TE, especially in the current version, provides a very easily approachable starting place for a new world. The machines and pipes require a variety of materials found a multiple different levels of the world, encouraging me to cave a bit, but don't typically require so much of any one material that I'm likely to be stymied or blocked if I can't find it.
The configurable sides for input and output (and always auto-outputting finished products) were, quite frankly, the coolest things EVER when I was first introduced to the mod. I'd been muddling along with wooden pipes and redstone engines and IC2 machines and then ... BAM! No more guesswork about what side to use for this or that. And the default choices were color-friendly enough that I didn't even have to resort to the color blind settings. There's not much in minecraft that being color blind is a problem for (the various mod ores are the biggest problem), but the fact that the team thought out the interface design to that degree was a pleasant thing for me, since that's actually a problem I have.
I've never had a TE machine or power system do something that I didn't expect or couldn't understand. The best case in point (and I apologize in advance if this devolves, but it's the best case in point). In 1.5.2, playing unleashed, I had a lava power system feeding into a redstone energy cell. I was using buildcraft pipes to run to each machine so that I could turn on and off the engines intelligently. I go to bed with a full energy cell and nothing working...I wake up the next morning with an empty cell, Lord only knows how much lava wasted, 5 magmatic engines trying their darnedest to keep up, and still no work being done. The only way to fix the problem was to break every pipe and put them all back down. After the third time, I switched to conduits and structure pipes and never had another problem. To this day I don't know what happened, but SOMETHING (one of 4 TE machines, 5 forestry machines, or a single assembly laser) was drawing power and doing no work at all, and it was drawing an incredible amount of power to do nothing.
Honestly, I seldom used TE for power generation, at least until TE3, and in my private pack I still don't (I prefer hydrogen generators from Mekanism
), but for everything else, the reasons above.
