I use IE, Chrome and Firefox interchangeably.
But then I have more than one machine, that range from XP to the 10 (no 8 though).
Firefox more frequently though.
Rare I use other than the big three as I log into other systems.
Some are better than others for blocking ads, etc. until you get some of the additional operating switches tweaked' and then there's not much of a difference.
Chrome is handy for quick pic searches.
It comes down to personal preference.
And yes a good idea to block all the tracking crap simply as they all try load cookies.
