what are the advantages and disadvantages???

 

You will get 100 opinions on why one is better then the other.
This should not be what you base your choice off of.
First you should make sure your tuner will tune either system.
Then you should look at both system's features & capabilities & and see which one best suites your goals.

 

Go with whatever your tuner is the most comfortable and best at tuning plain and simple.

 

I think you got your answer there. Closing.
