I avoid downshifting because of the stress on the transmission and the wear on the clutch. I'd rather replace my brake pads than have a clutch replaced or the whole transmission. The way I see it, you should know your car well enough to know what gear to put it in if you actually do need to take any sort of manuever. Just my 2 cents worth.

I coast coming to a stop. Helps with fuel economy also.

my sentiments exactly......why put added wear on a very expensive part....i'd much rather replace my brake pads than a clutch or tranny....i seriously doubt that either method makes much difference in fuel economy...

How much are you really going to save in gas by doing it one way or the other?
I am one to agree with less wear on the engine/clutch the better.
Here's another question tho...I recently had a European friend visit and he was apalled at how we all drive sticks...apalled that nobody seems to double clutch because it makes the driving experience much smoother. How many of you do/don't double clutch and what are your thoughts on it?

So so true. I recently learned how to match my RPM and shift(I forget what it's called) and for years I was too scared to try to figure it out cause I was only taught the clutch method.
My Dad rowed too but my gears don't slow down enough for my liking to warrant 4-1 shifts. Unless I'm either wanting to hear my engine sound cool or I have 3 miles before I come to a stop...

I mix the two...depends on what kind of stop I'm coming too...

You are wrong.
When you are coasting in gear the PCM shuts off the injectors in series. You are basically getting free mileage for no real fuel spent. The exhaust will be flat out lean. Engine braking (extreme vacuum) is by far the most efficient state an engine can be run in.
When you coast in neutral the PCM tries to idle up the engine and it also runs very rich.
Not only that but coasting out of gear is illegal and can be dangerous. The car is much more likely to stall. (no power steering or brakes)
Especially if you have to use the brakes which are powered by engine vacuum. Panic stops are not good when coasting in neutral because the sudden drop in manifold vacuum will probably stall the engine!

It's illegal?!?  I do it almost on a daily basis. On my way home from work there is a hill that's about a mile long, at the peak when going 50-55 I put it in neutral and coast all the way down. At the end, I have to slow down and turn and I've never had any problem with the brakes trying to stall the engine or anything like that. By the time I get to the bottom of the hill it isn't too uncommon to be going 60+.

You can't stall the engine while coasting. It can stall if you are in 5th gear and going at 5mph, you can't stall it in neutral, with or w/out the clutch depress.

Yea I usually will let the engine help come to a stop for me too. I don't usually press the clutch in until around 1500-2000rpm.
Failure is simply the opportunity to begin again, this time more intelligently.
