my fav....is the one that goes BANG each and every time I need it to
Seriously, that is like asking what tv show you like best, or what's the best car, etc, etc.
Depending on what each person owns....normally that will be what you will hear as "best" or "favorite" model.
If someone has any problems with a particular model (no matter the cause - and usually it is operator error) then that particular model or brand as a whole gets "black marked" as problem prone and stay away from it - bad juju
The worst part of it is...there is no way to tell just how many problems any particular brand really has, or what the true cause might be. As such, we tend to rely on "word of mouth" - such as in the case of..."Well my friend knows a guy, who lived next door to this other guy, who knew someone that was in the 'big one', that met this guy in a bar, who once saw this happen at the range...."
So...the one I like best...is the one that works for whatever I need it to do, whenever I need it to do it. I own, or have owned most of the major brands, have put together guns from parts from most of the major parts manufacturers, and have shot everything I have owned and still own to know what works for me. Sure there are some that I might say are a favorite, for whatever reason, but normally it is because it works well for that requirement.
But just to pick one brand out...I'll choose NEOPOLITAN
That being...the mutt that I put together from the parts that I have the most faith in and are matched to give the best performance with the ammunition, optics, and conditions that I will be using it in.
How's that for a PC answer?
