If you're on Jelly Bean, you have to add a different Browser to get Flash to work (why on earth would Adobe/Google not support flash, it's on about every page I open!).
Other browsers can wrap text better, give you more text size options (sometimes), give you more add-ons (Adblock), better tabbing, better bookmarking...
You just need to try a couple to see what you're missing (or not).
Chrome came on my Nexus 7, but I have it disabled. Been using Boat, but thinking of moving to "Naked", very fast....
