Again, it should be up to your ears. You need to listen to these and see what works for you, the drum sizes etc. If I recall, the Renown bass drum is 18" deep, not my cup of tea, but it may be yours. Come to think of it, the PDP may also have a deep bass drum?
Both of those kits get great reviews on here. The Renown would be classified upper intermediate/pro level, the PDP is intermediate. That is being reflected the price differences. To me those words don't matter, its how it sounds to you. If you were to sell again in the future, The resale value on the Gretsch will be good.
You can't go wrong with either of those kits.
