It's a hard question to answer, especially without throwing opinions everywhere.
Fact: All Piranha's function exactly the same
Fact: The differences between models are external
Opinion: I like the piranha composite trigger frames, but that's just me
Fact: Piranha's are great money buys, especially the lower end ones
Opinion: The higher end ones aren't worth it, either save the money and get a better gun or upgrade a lower end piranha
If you are buying for looks as well as function, the piranha pro is fine, but my first choice it to check out the BL and VTL first and see how much it would be to upgrade instead. If you want the anodizing enough to pay for it, go ahead.
The more important thing is that you are content with your purchase.
As far as it being tourney level, you will hear most people try to dissuade you of that view, but my opinion is that tourney teams win because of the attitude and skill and not the gun.
So to answer your 4 questions in order:
Yes, I believe it is good; you get what you pay for (generally).
The accuracy may or may not be good; some people get lucky with the stock barrel, most "upgrade" to an aftermarket one. This is also a function of paint->barrel match (at least In my experience).
Will the gun be able to keep up? Hmm… That's a difficult one, because it goes by two things: feed rate of the paintballs which is more a function of your loader and/or gravity and if you are running off CO2 or nitrogen/compressed air. It is unlikely you can outshoot your gun, but you can easily outshoot your loader and/or power source.
I would buy a piranha again if I were still a new player, but probably not the PRO just because it has some fancy things you can upgrade/don't need.
Like I said earlier, it is much more important that you be comfortable with the gun and your purchase.
