I am a massive Paiste fan, and having previously owned 2002 in 16", 18" and 19" I can give you some good feedback.
They are great if you are playing loud music, they sound beautiful out front. But what they lack is sensitivity for quieter music. They don't really have a good dynamic range because you need to play them a bit louder to get the most out of them. For what it's worth, I actually discovered the 2002 crashes by accident in a room full of Sabians that I was blindly hitting in the hopes of finding one I liked. Nothing to do with Bonham.
Now, I haven't bothered listening to Zildjian for a number of years simply because their cymbals were sounding mediocre for a very long time, so I can't give you any feedback on that front.
What I can suggest, however, is if you want cymbals that sound like the 2002s but have a better dynamic range and sensitivity - Giant Beat. I just bought a new 18" to go with my 20" yesterday, and I absolutely love it. Out of all the crash cymbals I've ever owned (mainly Paiste, but including Sabian and Zildjian) these are absolutely my favourite crashes ever.
But I actually just re-read your post and noticed that you said the pack has the 2002 Medium crashes. I would absolutely not use these ones if you are looking for versatility - they are heavier weighted and louder than the regular 2002 crashes which I owned.
So in this case, I think the A Zildjian crashes would be a better choice.
BUT BUT BUT BUT BUT!!!
Going back to what I said about the quality of the Zildjian cymbals over the last few years:
If you buy Zildjians in a pack, MAKE SURE YOU LISTEN TO THEM BEFORE YOU PAY ANY MONEY.
Make sure you are 100% certain that you are buying cymbals you like the sound of because it is a simple fact that some will sound worse than others. This is the one major problem with the casting manufacturing process for cymbals, in that you cannot guarantee consistent sound between identical models, there will always be subtle differences. This fact is true for Sabian, UFIP and Meinl - not just Zildjian.
But anyway, going back to the Paistes (again, because I am a massive fan), I think you should check out the Giant Beats. If you're a fan of Paiste's glassy sound as well as a 2002-type sound, but want something a little more versatile then these are definitely the way to go.
But you want the advice that I really want to give?
Go to a drum store. Hit cymbals. Buy the ones you like the sound of. Don't buy a package. Don't even look at the brands or model names if you can avoid it. Of course, if money is an issue then this is a lot harder to do, but this is still the best advice for buying cymbals that you can get. I know I've said I'm a massive Paiste fan, but I have 4 UFIP splashes, 2 Meinl Chinas and a Meinl ride cymbal - I only have Paiste in hats and crashes.
By the way, here is the Paiste website where you can listen to the cymbals. The recordings are very good and very accurate compared to hitting the cymbals in person:
