Why would you use D Addario gauge 9.5

 I bought this D' Addario EXL120plus gauge 9.5 electric guitar strings for my Epiphone SG Special 1. Im super happy with it. My guitar feels tighter and sounds crispier. I mean, fuller. 

I always struggle with the 9s on my SG special because it is soft and I tend to overbend. I also noticed that it's hard to tune. I feel that there's really wrong with gauge 9 on my SG special. Hence I bought and tried this D' Addario gauge 9.5.

Also worth saying that after I fitted the strings, it almost immediately adjusted and stayed in tune. Sometimes with other brands, it takes a while to stretch them and leave them for a day or two then it settles and stays in tune but this one is really good.

What is your favourite brand and gauge of strings for your SG guitar?
