Straight in or effects loop?
This is a follow up to my last question: /question/index?qid=20140...
I'm looking into a tube-based overdrive/boost pedal (Ibanez Tube King).
My question is: What total difference could I expect between running it straight in the front of my amp and putting it in my effects loop?
That would make my signal chain: Tube->SS->SS -OR- SS->Tube->SS.
Also, if I put the pedal in my effects loop, would hitting it with the signal from my amp's pre-amp damage the tube?
It occurred to me after I thought about it a bit that if I hit the tube-based pedal with a strong signal from my pre-amp it would eliminate the need for higher output pickups (making them optional rather than something I'd need to do to get the tone I want). BUT...I don't want to do that if I'm going to fry the tube with too strong of an incoming signal.
Thoughts?

There is no "right way" to do this. (contrary to what other posts suggest) It is a matter of taste and the actual components used. By placing overdrive pedal in front of the amp you will drive the preamp of the amp harder. This might be just the thing for an amp that does not have a lot of preamp gain but if you have an amp that has gain to spare than it might not be as desirable as running it through the loop where it will act as an extra gain stage after the preamp which is great for boosting a solo and slightly altering its tonal characteristic to make a lead stand out. (mid boost etc.)
A tube overdrive pedal uses built in op-amps to boost the tiny guitar signal up to a line level signal where the tube actually functions. (all pedals do this) By running it in the loop the pedals op amps do not need to boost the signal (which is why pedals are quieter in an effects loop). Some amps allow you to control the level of the effects send via a knob or a level switch. This can help you tailor the effects loop output to the appropriate level for optimal sound with your pedals. If you are worried about the tube in the pedal being hit too hard with the amps preamp signal than check the instructions for the pedal to see if there is any warning about this. If you are still unsure than you could contact them to inquire about it. My experience is that it should not matter if the proper levels are used.
As I have pointed out there is no "right way" your best bet is to experiment with each way and decide which is better for your set up and tastes.

Always use the boosters in front of the amp dont use it in the effects loop as it cuts the signal and sounds like totally sh1t, Guitar - Booster - Amp, this is the "right" way to do it.

Czar has a point. No right way but the way your ears enjoy it. That's how you get your own tone.
Loop vs direct was discussed a few days ago by Steve Vai who explained the difference and what he uses and what gives which results. I highly recommend listening to the guy who is known for knowing all about signal. http://kkguitar.com/guitar-gear/steve-vai-perfect-...
