The iPad has the best apps, period. If you're looking to only do showing off than any tablet will do. I am using an HP Touchpad that's running essentially stock Android 4.0.4, but if I could switch to an iPad I would, just for the better tablet apps, as table apps on Android are nowhere near as numerous, and not nearly as polished either. I do like my tablet a lot, but Android has a bigger learning curve than iOS, so I'd go for an iPad. If you can swing the new iPad, it's absolutely brilliant for showing photos due to its ultra-high res screen. If you want to save a little money for a lower res screen, then the iPad 2 is something to look at.
If you are used to Android, I'd honestly get the new Nexus 7. It's smaller at 7 inches, but runs stock Jelly Bean (Android 4.1), has a very high res screen and is only $199. If I were buying right now, I know I would have the Nexus 7 and new iPad as my only two choices, with the nod going to whichever is your preferred form factor or fits your budget.
